I still can repro the null deref with this patch applied.

see the attached file for dmesg output.

output of gdb:

(gdb) list *(blk_mq_flush_busy_ctxs+0x48)
0xffffffff8127b108 is in blk_mq_flush_busy_ctxs
(./include/linux/sbitmap.h:234).
229
230 for (i = 0; i < sb->map_nr; i++) {
231 struct sbitmap_word *word = &sb->map[i];
232 unsigned int off, nr;
233
234 if (!word->word)
235 continue;
236
237 nr = 0;
238 off = i << sb->shift;

when I change the "if (!word->word)" to "if (word && !word->word)"
I can get null deref at "nr = find_next_bit(&word->word, word->depth,
nr);". Seems like somehow word becomes NULL.

Adding the linux-nvme guys too.
Sagi has mentioned that this can be null only if we remove the tagset
while I/O is trying to get a tag and when killing the target we get into
error recovery and periodic reconnects, which does _NOT_ include freeing
the tagset, so this is probably the admin tagset.

Sagi,
you've mention a patch for centrelizing the treatment of the admin
tagset to the nvme core. I think I missed this patch, so can you please
send a pointer to it and I'll check if it helps ?
