fs/affs/file.c: unlock/release page on error

2015-03-25T23:20:31+00:00

When affs_bread_ino() fails, correctly unlock the page and release the page cache with proper error value. All write_end() should unlock/release the page that was locked by write_beg().

fs/affs/file.c: fix direct IO writes beyond EOF

2015-02-17T22:34:52+00:00

Use the same fallback to normal IO in case of write operations beyond EOF as fat direct IO. This patch fixes fsx file -d -Z -r 4096 -w 4096 Report: 129(129 mod 256): TRUNCATE DOWN from 0x3ff01 to 0xb3f6 130(130 mod 256): WRITE 0x22000 thru 0x2dfff (0xc000 bytes) HOLE Thanks to Jan for helping me on this problem. The ideal solution suggested by Jan Kara would be to use cont_write_begin() but affs direct_IO shouldn't be used a lot anyway...

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2014-06-12T17:30:18+00:00

Pull vfs updates from Al Viro: "This the bunch that sat in -next + lock_parent() fix. This is the minimal set; there's more pending stuff. In particular, I really hope to get acct.c fixes merged this cycle - we need that to deal sanely with delayed-mntput stuff. In the next pile, hopefully - that series is fairly short and localized (kernel/acct.c, fs/super.c and fs/namespace.c). In this pile: more iov_iter work. Most of prereqs for ->splice_write with sane locking order are there and Kent's dio rewrite would also fit nicely on top of this pile" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (70 commits) lock_parent: don't step on stale ->d_parent of all-but-freed one kill generic_file_splice_write() ceph: switch to iter_file_splice_write() shmem: switch to iter_file_splice_write() nfs: switch to iter_splice_write_file() fs/splice.c: remove unneeded exports ocfs2: switch to iter_file_splice_write() ->splice_write() via ->write_iter() bio_vec-backed iov_iter optimize copy_page_{to,from}_iter() bury generic_file_aio_{read,write} lustre: get rid of messing with iovecs ceph: switch to ->write_iter() ceph_sync_direct_write: stop poking into iov_iter guts ceph_sync_read: stop poking into iov_iter guts new helper: copy_page_from_iter() fuse: switch to ->write_iter() btrfs: switch to ->write_iter() ocfs2: switch to ->write_iter() xfs: switch to ->write_iter() ...
