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"

->splice_write() via ->write_iter()

2014-06-12T04:18:51+00:00

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]

fs/jfs/super.c: convert simple_str to kstr

2014-06-03T19:14:00+00:00

This patch replaces obsolete simple_str functions by kstr

use kstrtouint for
-uid_t ( __kernel_uid32_t )
-gid_t ( __kernel_gid32_t )
-jfs_sb_info->umask
-jfs_sb_info->minblks_trim
(all unsigned int)

newLVSize is s64 -> use kstrtol

Current parse_options behaviour stays the same ie it doesn't return kstr
rc but just 0 if function failed (parse_options callsites
return -EINVAL when there's anything wrong).

JFS: Check for NULL before calling posix_acl_equiv_mode()

2014-05-29T02:19:02+00:00

Check for NULL before using the acl in the access type switch
statement. This seems to be consistent with what is done in the JFFS
and ext4 filesystems and with the behaviour of JFS in the 3.13 kernel.
The bug seemed to be introduced in commit 2cc6a5a0.

The bug results in a kernel Oops, NULL dereference could not be handled
when accessing a JFS filesystem. The rdiff-backup process seemed to
trigger the bug. See also reported bug #75341:
