[Cluster-devel] [PATCH 4/6] GFS2: Hash the negative dentry during inode lookup

[Steven Whitehouse]

From: Benjamin Coddington <bcodd...@redhat.com>

Fix a regression introduced by:
6d4ade986f9c8df31e68 GFS2: Add atomic_open support
where an early return misses d_splice_alias() which had been
adding the negative dentry.
