Hi all, Could we in the end accept this patch? It'd fix the issue for now and I could set size of the XFS loop device smaller than 300 MB (better for embedded). i.e. 16 MB (or 32 or 64 MB or anything higher if XFS developers are convinced it's needed). As I wrote before I plan to suggest sizes: btrfs 110 MB the rest (ext[234], xfs, ntfs, vfat, exfat, tmpfs): 16 MB Based on quick test: https://lore.kernel.org/ltp/Yv%2FkVXSK0xJGb3RO@pevik/ btrfs: 109 MB, ntfs: 2 MB, ext3: 2 MB, ext[24]: 1 MB, vfat: 1 MB, exfat: 1 MB. Kind regards, Petr > mkfs.xfs since v5.19.0-rc1 [1] refuses to create filesystems < 300 MB. > Reuse workaround intended for fstests: set 3 environment variables: > export TEST_DIR=1 TEST_DEV=1 QA_CHECK_FS=1 > Workaround added to both C API (for .needs_device) and shell API (for > TST_NEEDS_DEVICE=1). > Fix includes any use of filesystem (C API: .all_filesystems, > .format_device, shell API: TST_MOUNT_DEVICE=1, TST_FORMAT_DEVICE=1). > Fixes various C and shell API failures, e.g.: > ./mkfs01.sh -f xfs > mkfs01 1 TINFO: timeout per run is 0h 5m 0s > tst_device.c:89: TINFO: Found free device 0 '/dev/loop0' > mkfs01 1 TFAIL: 'mkfs -t xfs -f /dev/loop0 ' failed. > Filesystem must be larger than 300MB. > ./creat09 > ... > tst_test.c:1599: TINFO: Testing on xfs > tst_test.c:1064: TINFO: Formatting /dev/loop0 with xfs opts='' extra opts='' > Filesystem must be larger than 300MB. > Link: https://lore.kernel.org/all/164738662491.3191861.15611882856331908607.stgit@magnolia/ > Reported-by: Martin Doucha <mdoucha@xxxxxxx> > Signed-off-by: Petr Vorel <pvorel@xxxxxxx> > --- > Dave, please next time remember there are other testsuites testing XFS, > not just fstests :).
