Add a pretty printer so the btree reserve cache can be seen in sysfs; as
it pins open_buckets we need it for tracking down open_buckets issues.

bcachefs: add counters for failed shrinker reclaim2024-05-09T20:24:29ZDaniel Hilldaniel@gluo.nz2022-09-30T03:37:15Zurn:sha1:bceacfa97ec8b67a76efad2f95899434230b317c
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.

bcachefs: Btree key cache instrumentation2024-05-08T21:29:20ZKent Overstreetkent.overstreet@linux.dev2024-04-20T18:49:22Zurn: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.
