We had a buggy release of bcachefs-tools that wasn't properly aligning
bucket sizes.
We can't ask users to reformat - and it's easy to teach the allocator to
make sure writes are properly aligned.

Replace these with proper private error codes, so that when we get an
error message we're not sifting through the entire codebase to see where
it came from.

bcachefs: Bail out early on alloc_nowait data updates2025-03-15T01:02:11ZKent Overstreet2025-01-19T18:55:33Zurn:sha1:7e9ed60f5fe58dd4b4b6dcf63e57154c6262a2af
If a data update doesn't want to block on allocations (promotes, self
healing on read error) - check if the allocation would fail before
kicking off the data update and calling into the write path.

bcachefs: dev_alloc_list.devs -> dev_alloc_list.data2024-12-21T06:36:22ZKent Overstreet2024-12-05T00:21:22Zurn:sha1:47d6ee766f8033563aff333f326378cd4b36a170
This lets us use darray macros on dev_alloc_list (and it will become a
darray eventually, when we increase the maximum number of devices).

bcachefs: Kill bch2_bucket_alloc_new_fs()2024-12-21T06:36:19ZKent Overstreet2024-11-25T04:28:21Zurn:sha1:828552ca74a45877dbf139b34c47d0f600a1e852
The early-early allocation path, bch2_bucket_alloc_new_fs(), is no
longer needed - and inconsistencies around new_fs_bucket_idx have been a
frequent source of bugs.

bcachefs: Make allocator stuck timeout configurable, ratelimit messages2024-08-08T01:04:55ZKent Overstreet2024-08-07T17:58:57Zurn:sha1:cecf72798b25fcb00303392407fccf500a746747
Limit these messages to once every 2 minutes to avoid spamming logs;
with multiple devices the output can be quite significant.
Also, up the default timeout to 30 seconds from 10 seconds.

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.

Wrapper around bch2_dev_have_ref() for open_buckets; we do guarantee
that the device an open_bucket points to exists.
