[LTP] [PATCH v6 0/8] shell: df01.sh: $TST_ALL_FILESYSTEMS

[Petr Vorel]

Hi all,

I finally merged this, with diff below.
In case I overlooked something in eb47b4497 ("tst_supported_fs: Support skip
list when query single fs") or there is other problem needed to be fixed before
release, I'll try to address it next week.

Thanks a lot to all reviewers for their time and patience.

Kind regards,
Petr
