[PATCH] btrfs: update some tests to be able to run with btrfs-progs v6.11

[PATCH] btrfs: update some tests to be able to run with btrfs-progs v6.11

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

In btrfs-progs v6.11 the output of the "filesystem show" command changed
so that it no longers prints blank lines. This happened with commit
4331bfb011bd ("btrfs-progs: fi show: remove stray newline in filesystem
show").

We have some tests that expect the blank lines in their golden output,
and therefore they fail with btrfs-progs v6.11.

So update the filter _filter_btrfs_filesystem_show to remove blank lines
and change the golden output of the tests to not expect the blank lines,
making the tests work with btrfs-progs v6.11 and older versions.

I got around to updating my test boxes to include this and did a full
re-run and I believe you may have missed removing the newline from the
golden outputs of btrfs/006 and btrfs/101. Sorry if I missed an updated
version or something.

I don't yet see this patch in the various branches I look at, so I
assume it's not to late to fold in those two changes as well. If not,
lmk, and I'm happy to send a follow up later.

Thanks,
Boris

No, I really missed those 2 tests, and I don't know why.

It hasn't been merged anywhere yet, so I've sent an updated v2.

[PATCH v2] btrfs: update some tests to be able to run with btrfs-progs v6.11

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

In btrfs-progs v6.11 the output of the "filesystem show" command changed
so that it no longers prints blank lines. This happened with commit
4331bfb011bd ("btrfs-progs: fi show: remove stray newline in filesystem
show").

We have some tests that expect the blank lines in their golden output,
and therefore they fail with btrfs-progs v6.11.

So update the filter _filter_btrfs_filesystem_show to remove blank lines
and change the golden output of the tests to not expect the blank lines,
making the tests work with btrfs-progs v6.11 and older versions.
