There are many ways now that writeback errors can be lost, such that fsync/fdatasync/msync return 0 when writeback actually failed. This pile contains a small set of cleanups and writeback error handling fixes that I was able to break off from the main pile (#2). Two of the patches in this pile are trivial. The exceptions are the patch to fix up error handling in write_one_page, and the patch to make JFS pay attention to write_one_page errors. Side note: I'm not going to send a PR for the remaining locking patches. Al picked up most of the file locking / fcntl patches from my series in one of his PRs, so all that's left is the l_pid rework from Ben. I think it's reasonable to give those a full cycle to soak in -next as they came in rather late in this cycle anyway. ---------------------------------------------------------------- Dave Kleikamp (1): JFS: do not ignore return code from write_one_page() Jeff Layton (3): mm: drop "wait" parameter from write_one_page() mm: clean up error handling in write_one_page fs: remove call_fsync helper function fs/exofs/dir.c | 2 +- fs/ext2/dir.c | 2 +- fs/jfs/jfs_metapage.c | 7 +++++-- fs/jfs/jfs_metapage.h | 1 + fs/minix/dir.c | 2 +- fs/sync.c | 2 +- fs/sysv/dir.c | 2 +- fs/ufs/dir.c | 2 +- include/linux/fs.h | 6 ------ include/linux/mm.h | 2 +- ipc/shm.c | 2 +- mm/page-writeback.c | 19 +++++++++---------- 12 files changed, 23 insertions(+), 26 deletions(-) --=20 Jeff Layton --=-o9ZW3LSCcJtG7Sc64oRH Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEES8DXskRxsqGE6vXTAA5oQRlWghUFAlleFksTHGpsYXl0b25A cmVkaGF0LmNvbQAKCRAADmhBGVaCFat5D/4752yoFv0ENrp6TK6dLmx1Hha5gdu1 IaCeKeA5GPARv5ViIRtrhP+WNBIvuLv1/06C+vq/3xZdNLTcWJ/Kvt82zrHHuza/ aHIahpHE/6xf3V5onqmrtZue7mcgVASMYo/6hqVSM8dZp4C7Bxk4dZczBlrkczc7 GBCOOhYj5faiaj+6XjqJblTXfF2rYAmDk5+HUHhbzocjiyXR5AW98yPxsWl2MjGN A3/IVxhb92PVIY1bIxTEIRoVcK8338gdJ6p63y6tfgnQMs/hiyB4OsbHvMz1Av+2 A3h2SDUUTWE1w5vEu4LPO/npcXgjqQNI3G1F1wR5nw8h5SNurzEgx/cjy+NExKXp 2nG82RwCAkUI1w+Ym9vrE/HMDInPrcf+fH39g7mQ9FnPyfJ6KWX9+FyS2uwNg+bV Dh5gdzVuGF3tnmZ9GhLH/l4e2fK7qbCopzMbV4SlTtfHZsQygT44zLC0rkNV96kP KzZPSR0SwwJodAfqRW0IP3b9ijGhuy+LvpZ8ikw5WPPNhZyA8WYAmIJwO1m4b0qb z6vBGpUExO+hjxuV7vuhBmiRIu2250/qUmC4lNaZjEHOUY3b7zQLT/v6lO2BaUny E8vncMI7NbSVJv4jMjG3F4PjESbE/0ysgjuL6AL9biJt4SVdq3P7HZj6XwI83+/2 70RouhoaiyPsKA== =uWw9 -----END PGP SIGNATURE----- --=-o9ZW3LSCcJtG7Sc64oRH--
