Subject: [PATCH v2 0/3] xfs_io: enable extsize and stat -v support for ext4

Changes since patch v1 [2]

  * Patch 1:
    - Remove extra brackets 
    - RVB from Christoph

Changes since rfc [1]

 * Patch 1: Don't add ext4 specific checks
 * Patch 2: 
   - Rather than adding a check for ext4, allow FS_IOC_GETXATTR to be
     called by any FS that supports it.

** Original Cover **

With ext4 extsize hints support being worked on, enable extsize 
command to be run on FSes other than xfs so ext4 can utilize it.
Also extend stat -v to perform FS_IOC_FSGETXATTR ioctl on ext4.

No funtional changes are intended for XFS.

Ojaswin Mujoo (3):
  include/linux.h: use linux/magic.h to get XFS_SUPER_MAGIC
  xfs_io: allow foreign FSes to show FS_IOC_FSGETXATTR details
  xfs_io: add extsize command support
