[LTP] [PATCH v2 1/3] nfs_lib.sh: Add nfs_get_remote_path()

[LTP] [PATCH v2 1/3] nfs_lib.sh: Add nfs_get_remote_path()

[Martin Doucha]

Sometimes it's necessary to manipulate remote NFS directory directly e.g.
to simulate external server activity. nfs_get_remote_path() will print
the remote path so that it can then be used by tst_rhost_run().

I'd use $FILE_COUNT (safe to use as help is run before setup, thus -n is not
processed).

If you run `nfs07.sh -hn 123`, your version will print that the default
is 123.

That would make the line over 80 characters and the number isn't that
important. Let's fix just the "fitler" typo.

Out of curiosity (as it's not anything important) not sure what's wrong on my
side (I tested it before I suggested it, I also reinstalled LTP to make sure
it's updated), but it works as expected:

I don't consider 80 as an issue as long as it's not over 100 chars (barier
increased also in mainline checkpatch.pl), but sure, these are really minor
issues, thus agree to fix just the typo.

Waiting little longer if Alexey has any comments and then merge.

Thanks a lot for very useful test case!

Kind regards,
Petr

Ah, sorry, I've put the arguments in the wrong order.
`nfs07.sh -n 123 -h` will overwrite $FILE_COUNT before printing usage info.
