439 /*These are handled in the xfs_ioctl.c . Before 2.4.28, XFS does not support these ioctls and

442 #define XFS_IOC_GETXFLAGS _IOR('f', 1, long)
443 #define XFS_IOC_SETXFLAGS _IOW('f', 2, long)

hence the error message.

Nathan asked a similar question, Forwarded message:Hi Nathan
Checking for an ext2 filesystem in chattr/lsattr is imho a bad idea.
The reiserfs people have a patch for it.
http://marc.theaimsgroup.com/?l=reiserfs&m=100218431021888&w=2
chattr/lsattr should just print "filesystem unsupported" or such when the
ioctl faild for an fs which doesn't support it.

while doing a chattr/lsattr on a file in XFS file system, I get following error :-chattr: Inappropriate ioctl for device while reading flags on <filename>
on strace, i found that chattr sends an ioctl command which is specific to EXT2. This
cmd is handled by ext2/ext3 and reiserfs but NOT by xfs.
can some one help by telling if this has been fixed in later versions ?
any pointer will be helpful ...
my kernel version: 2.4.20-20.7.XFS.1.3.1
thanks
