bcachefs: Compression levels This allows including a compression level when specifying a compression type, e.g. compression=zstd:15 Values from 1 through 15 indicate compression levels, 0 or unspecified indicates the default. For LZ4, values 3-15 specify that the HC algorithm should be used. Note that for compatibility, extents themselves only include the compression type, not the compression level. This means that specifying the same compression algorithm but different compression levels for the compression and background_compression options will have no effect.

bcachefs: Improved errcodes Instead of overloading standard error codes (EINTR/EAGAIN), and defining short lists of error codes in multiple places that potentially end up overlapping & conflicting, we're now going to have one master list of error codes. Error codes are defined with an x-macro: thus we also have bch2_err_str() now. Also, error codes have a class field. Now, instead of checking for errors with ==, code should use bch2_err_matches(), which returns true if the error is equal to or a sub-error of the error class. This means we can define unique errors for every source location where an error is generated, which will help improve our error messages. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

select QUOTACTL
bcachefs: Put erasure coding behind an EXPERIMENTAL kconfig option We still have disk space accounting changes coming for erasure coding, and the changes won't be as strictly backwards compatible as they'd ought to be - specifically, we need to start accounting striped data under a separate counter in bch_alloc (which describes buckets). A fsck will suffice for upgrading/downgrading, but since erasure coding is the most incomplete major feature of bcachefs it still makes sense to put behind a separate kconfig option, so that users are fully aware.

This enables the "erasure_code" filesysystem and inode option, which
organizes data into reed-solomon stripes instead of ordinary
replication.
WARNING: this feature is still undergoing on disk format changes, and
should only be enabled for testing purposes.

bcachefs: six locks: Simplify optimistic spinning osq lock maintainers don't want it to be used outside of kernel/locking/ - but, we can do better. Since we have lock handoff signalled via waitlist entries, there's no reason for optimistic spinning to have to look at the lock at all - aside from checking lock-owner; we can just spin looking at our waitlist entry.
