Some more mostly boring fixes, but some not
User reported ones:
- the BTREE_ITER_FILTER_SNAPSHOTS one fixes a really nasty performance
bug; user reported an unter initially taking 2 seconds and then ~2
minutes
- kill a __GFP_NOFAIL in the buffered read path; this was a leftover
from the trickier fix to kill __GFP_NOFAIL in readahead, where we
can't return errors (and have to silently truncate the read
ourselves).
bcachefs can't use GFP_NOFAIL for folio state unlike iomap based
filesystems because our folio state is just barely too big, 2MB
hugepages cause us to exceed the 2 page threshhold for GFP_NOFAIL.
additionally, the flags argument was just buggy, we weren't supplying
GFP_KERNEL previously (!).
