Hi Greg, Andrew Price has observed that mounting gfs2 filesystems is currently broken in the 4.15.y kernels. The reason is that commit 'gfs2: Fixes to "Implement iomap for block_map"' was cherry-picked from mainline in 4.15.5 without adding a commit that that commit depends on. Could you please fix that by adding the following commit to 4.15.y: e8b43fe0c1 gfs2: Clean up {lookup,fillup}_metapath In addition, could you please add the following commit to 4.15.y as well: 3b5da96e45 gfs2: Fixes to "Implement iomap for block_map" (2) Both commits can be cherry-picked cleanly. Thanks a lot, Andreas
