[Ojaswin Mujoo]

   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
