[Petr Vorel]

Hi Wei, Cyril,

Cyril, single note below can wait after the release.
Also, please have look if this fulfils your idea about testing the feature.

The test is running fine on github, please add it to

The point of SAFE_* functions/macros is to avoid having to check in the tests :).
Please remove these 2 lines.

Common patter for fgets() is to check for != NULL, then you don't need "*line &&":
	while (fgets(line, PATH_MAX, tune2fs) != NULL) {
		if (strstr(line, "Inode size:") && strstr(line, str_size)) {

check_inode_size() and the other 2 test functions return int but you don't use
the return value. Either use it or change return type to void.

While this works, it expect that nobody changes .filesystems below.

@Cyril: wouldn't be useful if the test itself had it's struct tst_fs member
from filesystems[i] available? Static variable, either pointer to the member or
instance of i from run_tcases_per_fs()?

Because we always expect filesystems (.type) is unique in .filesystems. But in
the future we might have test which uses several items in .filesystems with a
different data but an unique filesystem (not needed so far).

Kind regards,
Petr

If you don't add packages required in these 2 binaries into scripts in ci/ it
will not be tested in GitHub Actions.

very nit: I would personally add #define for 128 and 10240, but sure it's ok to
keep it hardcoded on 2 places.

I see busybox df implementation require mounting (unlike coreutils
implementation).

nit: As this is clearly completely unrelated change (but most of the git commit
message is in the description) it would be clearer to have it as a separate
change (as a previous commit, before adding packages).
+ mention in the commit message it's due busybox.
The subject of commit with ci/* changes could have prefix 'ci' (it's due
tst_format_device.sh, but you modify our CI).

nit: TST_MOUNT_DEVICE=1 implies TST_FORMAT_DEVICE=1 (not a mistake, but
TST_FORMAT_DEVICE=1 is not necessary).

I thought also use #define but i found and can not replace it in
"mkfs_opts = (const char *const []){"-I", "128", "-b", "1024", NULL}",
so i keep hardcoded number here.

Thanks for info. Sure, no problem.

Cc Cyril in case it's worth to fix it in metaparse.c.

The metaparse tool does macro expansion, that shouldn't be a problem.

Also metaparse only scans testcases/ directory during the build. The
lib/ directory is not parsed at all.

Yes, forcing double pass for the macro preprocessor is the correct
solution and We already have the same code in TST_TO_STR() in
tst_common.h

@Cyril Ah, I'm sorry I forget it's a library test, not an ordinary test.

@Wei I thought tested and see the problem, but you probably just suspect it
would be a problem.

Sorry i have not deep checked, since i put "INODE_SIZE" into mkfs_opts and
error report so i guess it not support it.

We should add e2fsprogs to ci env otherwise test cases
which need tune2fs/dumpe2fs in ci will be skipped.

For example following message:

We need to adjust 'char*[]' to new 'struct tst_cmd[]' since commit 39a284442.

[LTP] [PATCH v5 3/3] ci: Add e2fsprogs package for CI test

[Wei Gao via ltp]

We should add e2fsprogs to ci env otherwise test cases
which need tune2fs/dumpe2fs in ci will be skipped.

For example following message:
2025-09-24T09:00:56.9304198Z tst_cmd.c:268: TCONF: Couldn't find 'tune2fs' in $PATH
