This adds distinct counters for every reason the btree node shrinker can
fail to free an object - if our shrinker isn't making progress, this
will tell us why.

If we block on the allocator for more than 10 seconds, print out some
useful debugging info.

bcachefs: Btree key cache instrumentation2024-05-08T21:29:20ZKent Overstreet2024-04-20T18:49:22Zurn:sha1:5147b9ae768758982b196d1b259e6372e328955e
It turns out the btree key cache shrinker wasn't actually reclaiming
anything, prior to the previous patch. This adds instrumentation so that
if we have further issues we can see what's going on.
Specifically, sysfs internal/btree_key_cache is greatly expanded with
new counters, and the SRCU sequence numbers of the first 10 entries on
each pending freelist, and we also add trigger_btree_key_cache_shrink
for testing without having to prune all the system caches.

bcachefs: Move gc of bucket.oldest_gen to workqueue2024-05-08T21:29:20ZKent Overstreet2024-04-20T02:44:12Zurn:sha1:103304021e54bfb5cab9ba04cd5ef0dc2bf33888
This is a nice cleanup - and we've also been having problems with
kthread creation in the mount path.

bcachefs: iter/update/trigger/str_hash flag cleanup2024-05-08T21:29:18ZKent Overstreet2024-04-07T22:05:34Zurn:sha1:5dd8c60e1e044816d789098ce2454a130e06b03d
Combine iter/update/trigger/str_hash flags into a single enum, and
x-macroize them for a to_text() function later.
These flags are all for a specific iter/key/update context, so it makes
sense to group them together - iter/update/trigger flags were already
given distinct bits, this cleans up and unifies that handling.

sysfs is limited to PAGE_SIZE, and when we're debugging strange
deadlocks/priority inversions we need to see the full list.
