Bcachefs Merges New On-Disk Format Version For Linux 6.11, Working Toward Defrag
Ahead of the Linux 6.11-rc4 kernel release coming up later today, some more Bcachefs file-system patches were merged this weekend for this experimental copy-on-write file-system.
In addition to working toward defragmentation support, this latest Bcachefs fixes pull also takes care of a possible performance problem:"One performance issue we've observed is threads spinning when they should be waiting for dirty keys in the key cache to be flushed by journal reclaim, so we now have hysteresis for the waiting thread, as well as improving the tracepoint and a new time_stat, for tracking time blocked waiting on key cache flushing." More details on this latest batch of Bcachefs fixes from Kent Overstreet via this Git merge. Michael is also the lead developer of the Phoronix Test Suite, Phoromatic, and OpenBenchmarking.org automated benchmarking software.
