[Cluster-devel] [PATCH 2/4] GFS2: Read in rindex if necessary during unlink

From: Bob Peterson <rpeterso redhat com>

This patch fixes a problem whereby you were unable to delete
files until other file system operations were done (such as
statfs, touch, writes, etc.) that caused the rindex to be
read in.
