[PATCH 3/3] xfs: don't leak quotacheck dquots when cow recovery fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If we fail a mount on account of cow recovery errors, it's possible that
a previous quotacheck left some dquots in memory.  The bailout clause of
xfs_mountfs forgets to purge these, and so we leak them.  Fix that.
