Make a helper function nfs4_set_lease_period() and have nfs41_setup_state_renewal() and nfs4_do_fsinfo() use it. Signed-off-by: Trond Myklebust <[email protected]>
We don't want to miss a lease period renewal due to the TCP connection failing to reconnect in a timely fashion. To ensure this doesn't happen, cap the reconnection timer so that we retry the connection attempt at least every 1/2 lease period. Signed-off-by: Trond Myklebust <[email protected]>
…git/gregkh/usb Pull more USB updates from Greg KH: "Here are a few more straggler patches for USB for 4.8-rc1. Most of these are for the usb-serial driver tree. All of those have been in linux-next for a long time, but missed my previous pull request to you. The remaining change is to fix up a staging tree build error, due to some USB gadget driver changes that went in. I put it in this tree as it was for a USB driver and people are reporting the build error on your tree.

Pull more power management updates from Rafael Wysocki:
"A few more fixes and cleanups in the x86-64 low-level hibernation
code, PM core, cpufreq (Kconfig and intel_pstate), and the operating
points framework.
Specifics:
- Prevent the low-level assembly hibernate code on x86-64 from
referring to __PAGE_OFFSET directly as a symbol which doesn't work
when the kernel identity mapping base is randomized, in which case
__PAGE_OFFSET is a variable (Rafael Wysocki).
- Avoid selecting CPU_FREQ_STAT by default as the statistics are not
required for proper cpufreq operation (Borislav Petkov).
- Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of
processors where out-of-band (OBB) control of P-states is possible
and if that is in use, intel_pstate should not attempt to manage
P-states (Srinivas Pandruvada).
- Drop some unnecessary checks from the wakeup IRQ handling code in
the PM core (Markus Elfring).
- Reduce the number operating performance point (OPP) lookups in one
of the OPP framework's helper functions (Jisheng Zhang)"

Pull more ACPI updates from Rafael Wysocki:
"Two more fixes in ACPI drivers, one in the ACPI EC driver
(stable-candidate) and one in the ACPI button driver.
Specifics:
- An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's
method reentrancy limit to be exceeded for a _Qxx method due to a
large number of concurrent EC operations, so prevent that from
happening by moving the EC handling into a separate workqueue with
a limit on the number of concurrently executed work items (Lv
Zheng)
- Fix the cleanup code in the ACPI button driver that forgets to
clear two variables on exit which causes an error to occur on the
next attmpt to load the driver (Benjamin Tissoires)"

Pull block fixes from Jens Axboe:
"Here's the second round of block updates for this merge window.
It's a mix of fixes for changes that went in previously in this round,
and fixes in general. This pull request contains:
- Fixes for loop from Christoph
- A bdi vs gendisk lifetime fix from Dan, worth two cookies.
- A blk-mq timeout fix, when on frozen queues. From Gabriel.
- Writeback fix from Jan, ensuring that __writeback_single_inode()
does the right thing.
- Fix for bio->bi_rw usage in f2fs from me.
- Error path deadlock fix in blk-mq sysfs registration from me.
- Floppy O_ACCMODE fix from Jiri.
- Fix to the new bio op methods from Mike.
One more followup will be coming here, ensuring that we don't
propagate the block types outside of block. That, and a rename of
bio->bi_rw is coming right after -rc1 is cut.
- Various little fixes"

Commit 09ca4c9 (cpufreq: powernv: Replacing pstate_id with frequency table index) changes calc_global_pstate() to use cpufreq_table index instead of pstate_id. But in gpstate_timer_handler(), pstate_id was being passed instead of cpufreq_table index, which caused index_to_pstate() to access out of bound indices, leading to this crash. Adding sanity check for index and pstate, to ensure only valid pstate and index values are returned.

…m/linux/kernel/git/dgc/linux-xfs Pull more xfs updates from Dave Chinner: "This is the second part of the XFS updates for this merge cycle, and contains the new reverse block mapping feature for XFS. Reverse mapping allows us to track the owner of a specific block on disk precisely. It is implemented as a set of btrees (one per allocation group) that track the owners of allocated extents. Effectively it is a "used space tree" that is updated when we allocate or free extents. i.e. it is coherent with the free space btrees we already maintain and never overlaps with them. This reverse mapping infrastructure is the building block of several upcoming features - reflink, copy-on-write data, dedupe, online metadata and data scrubbing, highly accurate bad sector/data loss reporting to users, and significantly improved reconstruction of damaged and corrupted filesystems. There's a lot of new stuff coming along in the next couple of cycles,a nd it all builds in the rmap infrastructure. As such, it's a huge chunk of new code with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time kernel with this code in it is released. The new rmap enabled code regresses 3 xfstests - all are ENOSPC related corner cases, one of which Darrick posted a fix for a few hours ago. The other two are fixed by infrastructure that is part of the upcoming reflink patchset. This new ENOSPC infrastructure requires a on-disk format tweak required to keep mount times in check - we need to keep an on-disk count of allocated rmapbt blocks so we don't have to scan the entire btrees at mount time to count them. This is currently being tested and will be part of the fixes sent in the next week or two so users will not be exposed to this change" * tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (52 commits) xfs: move (and rename) the deferred bmap-free tracepoints xfs: collapse single use static functions xfs: remove unnecessary parentheses from log redo item recovery functions xfs: remove the extents array from the rmap update done log item xfs: in btree_lshift, only allocate temporary cursor when needed xfs: remove unnecesary lshift/rshift key initialization xfs: remove the get*keys and update_keys btree ops pointers xfs: enable the rmap btree functionality xfs: don't update rmapbt when fixing agfl xfs: disable XFS_IOC_SWAPEXT when rmap btree is enabled xfs: add rmap btree block detection to log recovery xfs: add rmap btree geometry feature flag xfs: propagate bmap updates to rmapbt xfs: enable the xfs_defer mechanism to process rmaps to update xfs: log rmap intent items xfs: create rmap update intent log items xfs: add rmap btree insert and delete helpers xfs: convert unwritten status of reverse mappings xfs: remove an extent from the rmap btree xfs: add an extent to the rmap btree ...

In most cases, EPERM is returned on immutable inode, and there're only a few places returning EACCES. I noticed this when running LTP on overlayfs, setxattr03 failed due to unexpected EACCES on immutable inode. So converting all EACCES to EPERM on immutable inode.

…rnel/git/jejb/binfmt_misc Pull binfmt_misc update from James Bottomley: "This update is to allow architecture emulation containers to function such that the emulation binary can be housed outside the container itself. The container and fs parts both have acks from relevant experts. To use the new feature you have to add an F option to your binfmt_misc configuration" From the docs: "The usual behaviour of binfmt_misc is to spawn the binary lazily when the misc format file is invoked. However, this doesn't work very well in the face of mount namespaces and changeroots, so the F mode opens the binary as soon as the emulation is installed and uses the opened image to spawn the emulator, meaning it is always available once installed, regardless of how the environment changes" * tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc: binfmt_misc: add F option description to documentation binfmt_misc: add persistent opened binary handler for containers fs: add filp_clone_open API

Commit abf5454 changed it from an 'rw' flags type to the newer ops based interface, but now we're effectively leaking some bdev internals to the rest of the kernel. Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead. Then we can also move op_is_write() and friends back under CONFIG_BLOCK protection. Reviewed-by: Mike Christie <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
