bcachefs was marked 'externally maintained' in 6.17 but the code
remained to make the transition smoother.
It's now a DKMS module, making the in-kernel code stale, so remove
it to avoid any version confusion.

These don't access global memory or defer pointer arguments - this
enables CSE optimizations.

bcachefs: Errcode tracepoint, documentation2024-03-14T01:22:25ZKent Overstreetkent.overstreet@linux.dev2024-02-22T03:10:09Zurn:sha1:eb386617be4bdfe02eb0972874f726e2bfc7a6e7
Add a tracepoint for downcasting private errors to standard errors, so
they can be recovered even when not logged; also, add some
documentation.

More reorganization, this splits up io.c into
- io_read.c
- io_misc.c - fallocate, fpunch, truncate
- io_write.c

bcachefs: Errcodes can now subtype standard error codes2023-10-22T21:09:40ZKent Overstreetkent.overstreet@linux.dev2022-09-18T19:43:50Zurn:sha1:5c1ef830f6786059f85bebe7501b63dffed0b633
The next patch is going to be adding private error codes for all the
places we return -ENOSPC.
Additionally, this patch updates return paths at all module boundaries
to call bch2_err_class(), to return the standard error code.

bcachefs: Improved errcodes2023-10-22T21:09:36ZKent Overstreetkent.overstreet@gmail.com2022-07-18T02:31:21Zurn:sha1:615f867c14b2d70efb02dafb8e668d984e74d0e3
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.
