[Cluster-devel] [PATCH] gfs2: Fixes to "Implement iomap for block_map" (2)

[Bob Peterson]

----- Original Message -----
| It turns out that commit 3229c18c0d6b2 'Fixes to "Implement iomap for
| block_map"' introduced another bug in gfs2_iomap_begin that can cause
| gfs2_block_map to set bh->b_size of an actual buffer to 0.  This can
| lead to arbitrary incorrect behavior including crashes or disk
| corruption.  Revert the incorrect part of that commit.
