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() ...

Pull nfsd updates from Bruce Fields: "The largest piece is a long-overdue rewrite of the xdr code to remove some annoying limitations: for example, there was no way to return ACLs larger than 4K, and readdir results were returned only in 4k chunks, limiting performance on large directories. Also: - part of Neil Brown's work to make NFS work reliably over the loopback interface (so client and server can run on the same machine without deadlocks). The rest of it is coming through other trees. - cleanup and bugfixes for some of the server RDMA code, from Steve Wise. - Various cleanup of NFSv4 state code in preparation for an overhaul of the locking, from Jeff, Trond, and Benny. - smaller bugfixes and cleanup from Christoph Hellwig and Kinglong Mee. Thanks to everyone! This summer looks likely to be busier than usual for knfsd.

fs/fat/: add support for DOS 1.x formatted volumes

2014-06-06T23:08:10Z

Add structure for parsed BPB information, struct fat_bios_param_block, and move all of the deserialization and validation logic from fat_fill_super() into fat_read_bpb(). Add a 'dos1xfloppy' mount option to infer DOS 2.x BIOS Parameter Block defaults from block device geometry for ancient floppies and floppy images, as a fall-back from the default BPB parsing logic. When fat_read_bpb() finds an invalid FAT filesystem and dos1xfloppy is set, fall back to fat_read_static_bpb(). fat_read_static_bpb() validates that the entire BPB is zero, and that the floppy has a DOS-style 8086 code bootstrapping header. Then it fills in default BPB values from media size and a table.[0] Media size is assumed to be static for archaic FAT volumes. See also: [1]. Fixes kernel.org bug #42617.

f2fs: avoid overflow when large directory feathure is enabled

2014-06-04T04:34:30Z

When large directory feathure is enable, We have one case which could cause overflow in dir_buckets() as following: special case: level + dir_level >= 32 and level < MAX_DIR_HASH_DEPTH / 2. Here we define MAX_DIR_BUCKETS to limit the return value when the condition could trigger potential overflow. Changes from V1 o modify description of calculation in f2fs.txt suggested by Changman Lee. Suggested-by: Changman Lee Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

nfsd4: allow exotic read compounds

2014-05-30T21:32:12Z

I'm not sure why a client would want to stuff multiple reads in a single compound rpc, but it's legal for them to do it, and we should really support it. Signed-off-by: J. Bruce Fields

Documentation: update /proc/stat "intr" count summary

2014-05-25T19:39:00Z

The sum at the beginning of line "intr" includes also unnumbered interrupts. It implies that the sum at the beginning isn't the sum of the remainder of the line, not even an estimation. Fixed the documentation to mention that. This behaviour was added to /proc/stat in commit a2eddfa95919 ("x86: make /proc/stat account for all interrupts") Signed-off-by: Jan Moskyto Matejka Signed-off-by: Randy Dunlap Signed-off-by: Linus Torvalds
