linux/kernel/sysctl_check.c
Tim Shimmin f3f0d7b026 [XFS] remove restricted chown parameter from xfs linux 
On Linux all filesystems are supposed to be operating under Posix'
restricted chown. Restricted chown means it restricts chown to the owner
unless you have CAP_FOWNER.

NOTE: that 2 files outside of fs/xfs have been modified too for this
change.
