- New on disk format version, bcachefs_metadata_version_disk_accounting_inum This adds one more disk accounting counter, which counts disk usage and number of extents per inode number. This lets us track fragmentation, for implementing defragmentation later, and it also counts disk usage per inode in all snapshots, which will be a useful thing to expose to users. - 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. And, various assorted smaller fixes. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAma/9QkACgkQE6szbY3K bnYcBw/+LBSZ415gWSjPktdecf5rc6K4KxETxAxV0f0KesYzxqAtQzN0SCDvKt65 3aALU03wM8vWITiLS38/ckT+j6S2BpXcOxdu/OC0nRYQEUg9ZLvqEG5lQ3a/LliV Q64N33qsSr6QaKszFllLYcN4tGduKg8HoMlHn6+vJ7HNPjdfv0HHERSUsc7K84/w jkRtDE2NxsRJZKMEvIFp8hd5KXUR5zyBz/kc4P0WliLXpSyJLITzhKw1JV7ikKVD 0mO2bJ/0i7wPIabAD2HJahvbC7fl+2fkYFxUJ2XnvMTgU/+QyeGHEufbcbVrVSp0 BpzBTmSMFbGXBkbQBruFX5rJetzXeBqdYf0Yfavd4KDhGvYlSfDZQUapXT1QKC2q aHSB/s+2r7Crr/MBJyjbeFgXFTNGvI5yerlbdp2yj1kxjYJHHaKrp6h7n6XXk21W /mGF5tkIMkFTv98rQnIaky4neJzOPsLTTgxeR8zEudCgMaVUqEcaMdIFvARDjY/3 n52VR0zl3olV3vu7LgHaHfgH6lfaMV0sHPaGNYGL0YL+bCJD+lYM8a6l9aaks8vk md7+mFcOS4FUdDdS8MEKIN/k/gkEOC/EpmI864i9rIl0SiNXNy7FPTDKON8b+Ury 5omBMUQMEe9Q/pgKGXfpJWFynhSPEVf4y1DIOsrXk/jeBqenFyo= =BPGT -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-08-16' of git://evilpiepirate.org/bcachefs Pull bcachefs fixes from Kent OverstreetL - New on disk format version, bcachefs_metadata_version_disk_accounting_inum This adds one more disk accounting counter, which counts disk usage and number of extents per inode number.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
