Remove bcachefs core code

2025-09-29T20:43:52+00:00

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.

bcachefs: struct alloc_request

2025-05-22T00:13:27+00:00

Add a struct for common state for satisfying an on disk allocation, instead of passing the same long list of items to every function. This will help with stack usage, performance, and perhaps enable some code cleanups. Signed-off-by: Kent Overstreet

bcachefs: Simplify bch2_write_op_error()

2025-03-24T13:50:36+00:00

There's no reason for the caller to do the actual logging, it's all done the same. Signed-off-by: Kent Overstreet

bcachefs: bch2_account_io_completion()

2025-03-15T01:02:16+00:00

We need to start accounting successes for every IO, not just failures, so introduce a unified hook for io completion accounting and convert io_read.c. Signed-off-by: Kent Overstreet

bcachefs: bch2_write_op_error() now prints info about data update

2025-03-15T01:02:14+00:00

A user has been seeing the "error verifying existing checksum while rewriting existing data (memory corruption?)" error. This generally indicates a hardware issue (and that may be the case here), but it might also indicate a bug, in which case we need more information to look for patterns.

bcachefs: Rename BCH_WRITE flags fer consistency with other x-macros enums

2025-03-15T01:02:11+00:00

The uppercase/lowercase style is nice for making the namespace explicit. Signed-off-by: Kent Overstreet

bcachefs: Improve decompression error messages

2025-01-25T19:43:13+00:00

Ratelimit them, and use the new bch2_write_op_error() helper that prints path and file offset. Reported-by: https://github.com/koverstreet/bcachefs/issues/819 Signed-off-by: Kent Overstreet

bcachefs: Rename BCH_WRITE_DONE -> BCH_WRITE_SUBMITTED

closures: CLOSURE_CALLBACK() to fix type punning

2023-11-24T05:29:58+00:00

Control flow integrity is now checking that type signatures match on indirect function calls. That breaks closures, which embed a work_struct in a closure in such a way that a closure_fn may also be used as a workqueue fn by the underlying closure code. So we have to change closure fns to take a work_struct as their argument - but that results in a loss of clarity, as closure fns have different semantics from normal workqueue functions (they run owning a ref on the closure, which must be released with continue_at() or closure_return()). Thus, this patc introduces CLOSURE_CALLBACK() and closure_type() macros as suggested by Kees, to smooth things over a bit. Suggested-by: Kees Cook Cc: Coly Li Signed-off-by: Kent Overstreet

bcachefs: Break up io.c

2023-10-22T21:10:12+00:00

More reorganization, this splits up io.c into - io_read.c - io_misc.c - fallocate, fpunch, truncate - io_write.c Signed-off-by: Kent Overstreet
