Yes, it should. init_rc() is getting called twice when common/rc is getting re-sourced. Maybe I can do like if $RECREATE_TEST_DEV || [ "$OLD_FSTYP" != "$FSTYP" ]; then <...> . common/rc # changes in this patch <...> elif [ "$OLD_TEST_FS_MOUNT_OPTS" != "$TEST_FS_MOUNT_OPTS" ]; then ... init_rc() # explicitly adding an init_rc() for this condition else init_rc() # # explicitly adding an init_rc() for all other conditions. This will prevent init_rc() from getting called twice during re-sourcing common/rc fi What do you think? > > Reviewed-by: "Darrick J.

Sounds fine as a mechanical change, but I wonder, should calling init_rc be explicit? There are not so many places that source common/rc: $ git grep 'common/rc' check:362:if ! . ./common/rc; then check:836: . common/rc common/preamble:52: . ./common/rc soak:7:. ./common/rc tests/generic/749:18:. ./common/rc (I filtered out the non-executable matches) I think the call in generic/749 is unnecessary and I don't know what soak does. But that means that one could insert an explicit call to init_rc at line 366 and 837 in check and at line 53 in common/preamble, and we can clean up one more of those places where sourcing a common/ file actually /does/ something quietly under the covers.

I think people just hope to import the helpers in common/rc mostly, don't want to run init_rc again. Maybe we can make sure the init_rc is only run once each time? E.g. if [ _INIT_RC != "done" ];then init_rc _INIT_RC="done" fi Or any better idea. Thanks, Zorro > > --D > > > > > > > > > Reviewed-by: "Darrick J.

This version looks good to me, I'll merge it with above changes. Reviewed-by: Zorro Lang <zlang@redhat.com> I'll push this patch (if it's passed the regression test) to fix current problem at first. About the common/rc:init_rc we're talking about, I think we can keep talking, and change that in another patch if need. Thanks for fixing this.

Okay just to clear my understanding, do you mean that the call to init_rc() be removed from common/rc file and the places which actually need the call to init_rc, explicitly calls init_rc() instead of sourcing ". common/rc" and making common/rc do something under the cover? --NR > > (Unless the maintainer is ok with the status quo...?) > > --D > >>> Reviewed-by: "Darrick J.

However, after thinking a bit more, I like Darrick's idea to remove the call to init_rc from common/rc and explicitly calling them explicitly whenever necessary makes more sense. This also makes the interface/reason to source common/rc more meaningful, and also not making common/rc do something via init_rc silently.

Sorry I'm on a travel, reply you late. I don't like to run codes in include files either :) If we remove the init_rc calling from common/rc we might need to do 2 things: 1) xfstests/check needs to run init_rc, calls it in check properly. 2) Now each sub-cases run init_rc when they import common/rc, I think we can call init_rc in common/preamble:_begin_fstest().

Bug Description: _test_mount function is failing with the following error: ./common/rc: line 4716: _xfs_prepare_for_eio_shutdown: command not found check: failed to mount /dev/loop0 on /mnt1/test when the second section in local.config file is xfs and the first section is non-xfs. It can be easily reproduced with the following local.config file [s2] export FSTYP=ext4 export TEST_DEV=/dev/loop0 export TEST_DIR=/mnt1/test export SCRATCH_DEV=/dev/loop1 export SCRATCH_MNT=/mnt1/scratch [s1] export FSTYP=xfs export TEST_DEV=/dev/loop0 export TEST_DIR=/mnt1/test export SCRATCH_DEV=/dev/loop1 export SCRATCH_MNT=/mnt1/scratch ./check selftest/001 Root cause: When _test_mount() is executed for the second section, the FSTYPE has already changed but the new fs specific common/$FSTYP has not yet been done. Hence _xfs_prepare_for_eio_shutdown() is not found and the test run fails. Fix: Remove the additional _test_mount in check file just before ". commom/rc" since ". commom/rc" is already sourcing fs specific imports and doing a _test_mount.
