[LTP] [PATCH 4/4] libswap: add Btrfs noCOW attribute setting for swap files

[Petr Vorel]

Hi Li,

testing the patchset on SLES, at least swapon01 reports some results
on systems with TMPDIR on tmpfs or btrfs.

Therefore I agree it'd be good to use the same approach for all swapon* and
swapoff* tests.

I would be ok to get it to the release (generally patchset LGTM), but depends on
your and Cyril's time (no problem to postpone it).

Kind regards,
Petr
