Hi All,

This updated patchset is on top of ad81f054 of xfs git (3.11-rc1). The
patches do not convert the id's returned from bulkstat, since bulkstat
cannot be called from inside a userns right now anyway since the caller
must be CAP_SYS_ADMIN in init_user_ns.

Changes since v3 patchset:
 - export inode_capable() for building xfs as a module
 - implement Brian's proposal for an internal flag to indicate to
   xfs_inode_free_eofblocks() that it should do a permission check.
   ioctl callers will always set this flag, which is simpler than
   making them specify XFS_EOF_FLAGS_UID or XFS_EOF_FLAGS_GID,
   internal callers can leave it unset so no permission checking is
   done
 - take Brian's suggestion on moving the policy from the conversion
   function into the ioctl code, and moving stuff to xfs_icache.h
