Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull misc filesystem fixes from Jan Kara:
 "Several ACL related fixes for ext2, reiserfs, and hfsplus.

  And also one minor isofs cleanup"

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  hfsplus: Don't clear SGID when inheriting ACLs
  isofs: Fix off-by-one in 'session' mount option parsing
  reiserfs: preserve i_mode if __reiserfs_set_acl() fails
  ext2: preserve i_mode if ext2_set_acl() fails
  ext2: Don't clear SGID when inheriting ACLs
  reiserfs: Don't clear SGID when inheriting ACLs
