bcachefs: Discard, invalidate workers are now per device 2024-06-25T22:47:55+00:00 Kent Overstreet kent.overstreet@linux.dev 2024-06-23T04:53:44+00:00 64ee1431cc7d11e01a1007ead0afe737781cbbab There's no reason for discards to be single threaded across all devices; this will improve performance on multi device setups. Additionally, making them per-device simplifies the refcounting on bch_dev->io_ref; we now hold it for the duration that the discard path is running, which fixes a race between the discard path and device removal.

bcachefs: Allocator prefers not to expand mi.btree_allocated bitmap 2024-05-08T21:29:24+00:00 Kent Overstreet kent.overstreet@linux.dev 2024-04-20T20:25:34+00:00 c6705091342c06c963015dac07ede417d2e0ad04 We now have a small bitmap in the member info section of the superblock for "regions that have btree nodes", so that if we ever have to scan for btree nodes in repair we don't have to scan the whole device(s). This tweaks the allocator to prefer allocating from regions that are already marked in this bitmap. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Much nicer to just trace a string, and then we can build nicely formatted output with printbufs. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
