Sorry for the previous reply in HTML format which is not delivered to the mail list. I mean there is already xfstests generic/405 for the situation. Thin provision devices need to call dmsetup to setup. I wonder If calling dmsetup in progs tests is acceptable or not. If it is, I will do it.

Yes dmsetup is already used eg in test mkfs-tests/005-long-device-name-for-ssd . -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

when mkfs.btrfs on a thin provision device which has very small backing size and big virtual size, all code works well in mkfs.btrfs until close_ctree() is called. close_ctree() fails to sync device due to small backing size while closing devices. However, mkfs returns 0 in such situation which causes failure of xfstests generic/405. So, let mkfs returns nonzero value if previous steps succeeded but close_ctree() failed. Then xfstests generic/405 passes now. Signed-off-by: Su Yue <suy.fnst@cn.fujitsu.com> --- mkfs/main.c | 6 ++++++ 1 file changed, 6 insertions(+)
