[LTP] [linux-next:master] [block/bdev] 3c20917120: BUG:sleeping_function_called_from_invalid_context_at_mm/util.c

[Darrick J. Wong]

Hi Luis,

I'm not sure if this is related, but I'm seeing the same "BUG: sleeping
function called from invalid context at mm/util.c:743" message when
running fstests on XFS.  Nothing exciting with fstests here other than
the machine is arm64 with 64k basepages and 4k fsblock size:

MKFS_OPTIONS="-m metadir=1,autofsck=1,uquota,gquota,pquota"

--D
