Hi Amir, Jan,

LTP tested on btrfs on TMPDIR is skipped with TCONF:
# TMPDIR=/var/tmp ./fanotify23
tst_tmpdir.c:316: TINFO: Using /var/tmp/LTP_fanzN3sOS as tmpdir (btrfs filesystem)
tst_device.c:98: TINFO: Found free device 0 '/dev/loop0'

The same is fanotify22.c
fanotify22.c:296: TCONF: FAN_FS_ERROR not supported on ext4 filesystem

They work on tmpfs on TMPDIR:

# ./fanotify23
tst_tmpdir.c:316: TINFO: Using /tmp/LTP_fanh6TUn4 as tmpdir (tmpfs filesystem)
tst_device.c:98: TINFO: Found free device 0 '/dev/loop0'

Is there a way to avoid TCONF on btrfs?

# df -hT /var/tmp/ /tmp/
Filesystem     Type   Size  Used Avail Use% Mounted on
/dev/vda2      btrfs   28G   24G  1.6G  94% /var
tmpfs          tmpfs  1.4G   32K  1.4G   1% /tmp

Kind regards,
Petr
