[LTP] [PATCH v2 3/4] tst_test.sh: Improve pattern for allowed variables

[Petr Vorel]

to allow using '... $TST_FOO'

i.e. without filtering '
EXPECT_PASS "grep '$TST_MNTPOINT $TST_FS_TYPE' /proc/mounts"
would produce warning:
tst_mount_device 1 TWARN: Reserved variable TST_FS_TYPE' used!
because sed filters it as: FS_TYPE'

Will be needed for next commit.

[LTP] [PATCH v2 4/4] shell: Add test for TST_MOUNT_DEVICE=1

[Petr Vorel]

Unfortunately GitHub Actions don't have loop devices, thus cannot be run
in CI:

tst_format_device 1 TINFO: timeout per run is 0h 5m 0s
/__w/ltp/ltp/lib/tst_device.c:139: TINFO: No free devices found

Hi,

I forget to remove TST_CLEANUP=tst_umount.

Therefore there is an error:
df01 13 TINFO: The '/tmp/LTP_df01.UaDhMw4Ifq/mntpoint' is not mounted, skipping umount

If this is the only error, I'll fix it during merge.

Kind regards,
Petr

Here.
I'll fix it before merge (if it's the only change requested).
