Bug 152111

Hello!

Btrfs fails to load on my SPARC T5-2 if kernel (git describe v4.8-rc1-121-g4b9eaf3) compiled with:

CONFIG_BTRFS_FS=m
CONFIG_BTRFS_FS_POSIX_ACL=y
CONFIG_BTRFS_FS_CHECK_INTEGRITY=y
CONFIG_BTRFS_FS_RUN_SANITY_TESTS=y
CONFIG_BTRFS_DEBUG=y
CONFIG_BTRFS_ASSERT=y

It fails to load with the following messages:

[935325.023060] Btrfs loaded, crc32c=crc32c-generic, debug=on, assert=on, integrity-checker=on

I have reported it in [1] and there's a patch [2] for v4.7-rc7 kernel, but it does not applies cleanly to current git kernel.

I've made some btrfs fs tests (using xfstests suite) after applying [2] patch with 4.7-rc7 kernel and tests run successfully (i.e. with ok result, without errors).

Can someone refresh patch in [2] to support current git kernel and push it to git?
 
Thanks.
