This patch checks for this condition when this function is called from gfs2_mblk_search() In addition, the use of this particular function in other places in the code has been dropped by means of a general clean up of gfs2_inplace_reserve(). This function is now much easier to follow. Also the setting of the rgd->rd_last_alloc field is corrected. Signed-off-by: Steven Whitehouse --- Reading git-diff-tree failed
