Now that 3.1's out and the interfaces have stabilized we'll get support for it in to the next release candidate. |

Prior to Linux 3.1 the kern_path_parent symbol was exported for use by kernel modules. As of Linux 3.1 it is now longer easily available. To handle this case the spl will now dynamically look up address of the missing symbol at module load time. Signed-off-by: Brian Behlendorf <[email protected]> Issue #52

Preferentially use the vfs_fsync() function. This function was initially introduced in 2.6.29 and took three arguments. As of 2.6.35 the dentry argument was dropped from the function. For older kernels fall back to using file_fsync() which also took three arguments including the dentry. Signed-off-by: Brian Behlendorf <[email protected]> Issue #52

As of Linux 3.1 the shrink_dcache_memory and shrink_icache_memory functions have been removed. This same task is now accomplished more cleanly with per super block shrinkers. This unfortunately leaves us no easy way to support the dnlc_reduce_cache() function. This support has always been entirely optional. So when no reasonable interface is available allow the dnlc_reduce_cache() function to effectively become a no-op. The downside of this change is that it will prevent the zfs arc meta data limts from being enforced. However, the current zfs implementation in this regard is already flawed and needs to be reworked. If the arc needs to enfore a meta data limit it will need to be extended to coordinate directly with the zpl. This will allow us to drop all this compatibility code and get more fine grained control over the cache management. Signed-off-by: Brian Behlendorf <[email protected]> Issue #52

Closing issue, the required compatibility code has been merged in to master. Please open a new issue if you observe any issues, the changes have been tested under fedora 16 which using a 3.1 based kernel. |
