GFS2: Don't withdraw on partial rindex entries
ince gfs2 writes the rindex file a block at a time, and releases the exclusive lock after each block, it is possible that another process will grab the lock in the middle of the write. Since rindex entries are not an even divisor of blocks, that other process may see partial entries. On grows, this is fine. The process can simply ignore the the partial entires. Previously, the code withdrew when it saw partial entries. Now it simply ignores them. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
