  it's both faster (in case when file has been opened for write) and cleaner.

  Some ioctl()s can cause writes to the filesystem. Take these, and make them
  use mnt_want/drop_write() instead.

  The ioctls were already compatible except for the actual values so this

  Convert jfs_ioctl over to not use the BKL. The only potential race
  I could see was with two ioctls in parallel changing the flags
  and losing the updates. Use the i_mutex to protect against this.

• e47776a0a   Forbid user to change file flags on quota files ... Browse Code »

  Forbid user from changing file flags on quota files. User has no bussiness
  in playing with these flags when quota is on. Furthermore there is a
  remote possibility of deadlock due to a lock inversion between quota file's
  i_mutex and transaction's start (i_mutex for quota file is locked only when
  trasaction is started in quota operations) in ext3 and ext4.

• 3bd858ab1   Introduce is_owner_or_cap() to wrap CAP_FOWNER use with fsuid check ... Browse Code »

  Introduce is_owner_or_cap() macro in fs.h, and convert over relevant
  users to it. This is done because we want to avoid bugs in the future
  where we check for only effective fsuid of the current task against a
  file's owning uid, without simultaneously checking for CAP_FOWNER as
  well, thus violating its semantics.
  [ XFS uses special macros and structures, and in general looked ...
  untouchable, so we leave it alone -- but it has been looked over. ]

  The (current->fsuid != inode->i_uid) check in generic_permission() and
  exec_permission_lite() is left alone, because those operations are
  covered by CAP_DAC_OVERRIDE and CAP_DAC_READ_SEARCH. Similarly operations
  falling under the purview of CAP_CHOWN and CAP_LEASE are also left alone.

• 3e2221c73   Copy i_flags to jfs inode flags on write ... Browse Code »

  This mirrors Jan Kara's patches for ext3. This patch makes sure that
  changes made to inode->i_flags are reflected on disk for jfs. It also
  moves a call of jfs_set_inode_flags() to be more consistent with where
  jfs_get_inode_flags() is called.

  Move common FS-specific ioctls from linux/ext2_fs.h to linux/fs.h as FS_IOC_*
  and FS_IOC32_* and have the users of them use those as a base.

  Also move the GETFLAGS/SETFLAGS flags to linux/fs.h as FS_*_FL macros, and then
  have the other users use them as a base.
