because there are some problems with at least vfat, exfat and tmpfs (on
nfs-utils < 2) instead of testing on all available filesystems, test
just on modern Linux filesystems btrfs, ext4, xfs.
Use variables:
* TST_ALL_FILESYSTEMS=1 to run on all filesystems
* TST_FORMAT_DEVICE=1 to get loop device formatted
* TST_MOUNT_DEVICE=1 to get it mounted
Filesystems (tested the usual LTP way on loop device) are used for
server side (exportfs), client side (NFS mount) is kept outside of it.
For some reason umounting needs some time before NFS server stops using
underlying loop device. Also exportfs needs time before files can be
removed. Otherwise second umounting fails:
nfs07 4 TINFO: Cleaning up testcase
umount: /var/tmp/LTP_nfs07.FNZ7yCbqZe/mntpoint: target is busy.
nfs07 4 TINFO: umount(/var/tmp/LTP_nfs07.FNZ7yCbqZe/mntpoint) failed, try 1 ...
nfs07 4 TINFO: Likely gvfsd-trash is probing newly mounted fs, kill it to speed up tests.
umount: /var/tmp/LTP_nfs07.FNZ7yCbqZe/mntpoint: target is busy.
Solved with adding sleep for 2 sec after first umount and sleeps for 1 sec after exportfs.
Second umount of the loop device in tst_test.sh works without any extra
sleep.
