@tuxoko due to the recent flakeyness of the buildbot a regression slipped in from #4951. The wrong interface was being used 2.6.32 kernels resulting in a panic with zconfig.sh test 5. This change reorders the checks (similar to how they were before) to ensure the right interface is used. Can you review this. |

Can you add a comment in the code so it won't happen again? Otherwise LGTM. Is there a way we can get panic stack trace out of buildbot? |
The HAVE_BIO_RW_* #ifdef's must appear before REQ_* #ifdef's in the bio_is_flush() and bio_is_discard() macros. Linux 2.6.32 era kernels defined both of values and the HAVE_BIO_RW_* must be used in this case. This resulted in a panic in zconfig test 5.

Good, idea. Updated with a comment.
In theory yes, but in practice I haven't found a 100% reliable way to do this which is frustrating. |
