While running xfstest 280, we occasionally got such error:
setquota: Cannot set quota for user 0 from kernel on
/dev/mapper/xfstests-disk1: No such device
setquota: Cannot write quota for 0 on /dev/mapper/xfstests-disk1: No such
setquota calls syscall quotactl, and the kernel will wait for the filesystem
to unfreeze and then performs command. Then kernel will double check if the
device is still mounted. If not, an ENODEV will be thrown.
While in the testcase, unfreeze and umount might be so close that the device
got umounted before quotactl is performed.
