[Cluster-devel] [GFS2] Pre-pull patch posting (fixes)

[Steven Whitehouse]

Hi,

Here are a couple of GFS2 fixes. Both are one-liners,

Steve.

[Cluster-devel] [PATCH 1/2] GFS2: Fix error code

[Steven Whitehouse]

From: Abhijith Das <adas@redhat.com>

We need this one-liner to signal the mount helper of the 'insufficient journals' condition.

[Cluster-devel] [PATCH 2/2] GFS2: Fix bmap allocation corner-case bug

[Steven Whitehouse]

This patch solves a corner case during allocation which occurs if both
metadata (indirect) and data blocks are required but there is an
obstacle in the filesystem (e.g. a resource group header or another
allocated block) such that when the allocation is requested only
enough blocks for the metadata are returned.

By changing the exit condition of this loop, we ensure that a
minimum of one data block will always be returned.
