Subject: xfs: don't release log intent items when recovery fails
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=384ff09ba2e5170a0eec8d4af57065a47c3f8ef2;p=linux.git

xfs: don't release log intent items when recovery fails

Nowadays, log recovery will call ->release on the recovered intent items
if recovery fails.  Therefore, it's redundant to release them from
inside the ->recover functions when they're about to return an error.
