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 two sleeps for 1 sec (using less is not enough,
specially for nfs07.sh).
Skipping some problematic filesystems:
* exfat
Although it works on some systems (e.g. openSUSE Tumbleweed
with kernel 6.2.8-1-default, nfs-utils 2.6.2, exfatprogs 1.2.0), it
fails on other systems (e.g. SLES 15-SP4 with kernel 5.14.21, nfs-utils
2.1.1, exfatprogs 1.0.4 or Debian 12 bookworm with kernel 6.1.0-6-amd64,
nfs-utils 2.6.2, exfatprogs 1.2.0)
* tmpfs on nfs-utils < 2
tmpfs fails on nfs-utils 1.3.3:
nfs07 1 TINFO: mount.nfs: (linux nfs-utils 1.3.3)
nfs07 1 TINFO: setup NFSv4.2, socket type tcp
nfs07 1 TINFO: Mounting NFS: mount -v -t nfs -o proto=tcp,vers=4.2 10.0.0.2:/tmp/LTP_nfs07.cex71Q5bxw/mntpoint/4.2/tcp /tmp/LTP_nfs07.cex71Q5bxw/4.2/0
mount.nfs: mount(2): No such file or directory
mount.nfs: mounting 10.0.0.2:/tmp/LTP_nfs07.cex71Q5bxw/mntpoint/4.2/tcp failed, reason given by server: No such file or directory
mount.nfs: timeout set for Mon Apr 24 21:34:02 2023
mount.nfs: trying text-based options 'proto=tcp,vers=4.2,addr=10.0.0.2,clientaddr=10.0.0.1'
nfs07 1 TBROK: mount command failed
But it works on nfs-utils 2.1.1 on SLE15-SP4.

I'd expect that c5528f40 ("Fix NFSv4 export of tmpfs filesystems")
from 2.5.4 is needed, but it works in SLE 15-SP4 which is 2.1.1 and this
patch was not backported.
