f2fs: expose some sectors to user in inline data or dentry case

2018-02-13T18:42:09Z

commit 5b4267d195dd887c4412e34b5a7365baa741b679 upstream. If there's some data written through inline data or dentry, we need to shouw st_blocks. This fixes reporting zero blocks even though there is small written data.

fs: Give dentry to inode_change_ok() instead of inode

2017-02-23T03:53:52Z

commit 31051c85b5e2aaaf6315f74c72a732673632a905 upstream. inode_change_ok() will be resposible for clearing capabilities and IMA extended attributes and as such will need dentry. Give it as an argument to inode_change_ok() instead of an inode. Also rename inode_change_ok() to setattr_prepare() to better relect that it does also some modifications in addition to checks. Reviewed-by: Christoph Hellwig Signed-off-by: Jan Kara [bwh: Backported to 3.16: - Drop changes to orangefs, overlayfs - Adjust filenames, context - In nfsd, pass dentry to nfsd_sanitize_attrs() - Update ext3 as well] Signed-off-by: Ben Hutchings

Revert "fs: Give dentry to inode_change_ok() instead of inode"

2017-02-23T03:53:52Z

This reverts commit be9df699432235753c3824b0f5a27d46de7fdc9e, which was commit 31051c85b5e2aaaf6315f74c72a732673632a905 upstream. The backport breaks fuse and makes a mess of xfs, which can be improved by picking further upstream commits as I should have done in the first place. Signed-off-by: Ben Hutchings

f2fs: fix not to allocate unnecessary blocks during fallocate

2014-06-23T01:05:08Z

This patch fixes the fallocate bug like below. (See xfstests/255) In fallocate(fd, 0, 20480), expand_inode_data processes for (index = pg_start; index <= pg_end; index++) { f2fs_reserve_block(); ... } So, even though fallocate requests 20480, 5 blocks, f2fs allocates 6 blocks including pg_end. So, this patch adds one condition to avoid block allocation. Signed-off-by: Jaegeuk Kim

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() ...

->splice_write() via ->write_iter()

iter_file_splice_write() - a ->splice_write() instance that gathers the pipe buffers, builds a bio_vec-based iov_iter covering those and feeds it to ->write_iter(). A bunch of simple cases coverted to that... [AV: fixed the braino spotted by Cyrill] Signed-off-by: Al Viro
