This is a stall, but it involves __getblk_gfp. Is it the same bug as
"INFO: task hung in generic_file_write_iter":
https://syzkaller.appspot.com/bug?id=8afdd02539e35fc02ac7699014bc54a87fdd8dc0
which will be fixed with "blockdev: Fix livelocks on loop device".

This bug also has 10 other duplicates:
