Hi Nathan
Checking for an ext2 filesystem in chattr/lsattr is imho a bad idea.
The reiserfs people have a patch for it.

chattr/lsattr should just print "filesystem unsupported" or such when the
ioctl faild for an fs which doesn't support it.

Hi,
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
