Subject[v2.6.34-stable 11/77] cifs: fix cifs stable patch cifs-fix-oplock-break-handling-try-2.patch
From: Suresh Jayaraman <>

This is a commit scheduled for the next v2.6.34 longterm release.
If you see a problem with using this for longterm, please comment.

commit 4708ad6374f07cdfb379c5d4100125e2cfd339d9 in v2.6.32.x stable

The stable release added the upstream commit
12fed00de963433128b5366a21a55808fab2f756. However, one of the hunks of
the original patch seems missing from the stable backport which can be
found here:

This hunk corresponds to the change in is_valid_oplock_break() at

This patch backports the missing hunk and is against
linux-2.6.32.y stable kernel.

[PG: I incorrectly dropped the same hunk in v2.6.34.9-152-g0c55f20
since the code in question was relocated/rewritten in e66673e39a ]
