Subject: dcache: don't clear DCACHE_DISCONNECTED too early
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f80de2cde10350b8d146e375ff8b634e72e6a827;p=deliverable%2Flinux.git

dcache: don't clear DCACHE_DISCONNECTED too early

DCACHE_DISCONNECTED should not be cleared until we're sure the dentry is
connected all the way up to the root of the filesystem.  It *shouldn't*
be cleared as soon as the dentry is connected to a parent.  That will
cause bugs at least on exportable filesystems.
