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: Call bch2_fs_init_rw() early if we'll be going rw

2025-06-16T23:04:48+00:00

kthread creation checks for pending signals, which is _very_ annoying if we have to do a long recovery and don't go rw until we've done significant work. Check if we'll be going rw and pre-allocate kthreads/workqueues. Signed-off-by: Kent Overstreet

bcachefs: bch2_fs_emergency_read_only2()

2025-05-22T00:14:56+00:00

More error message cleanup: instead of multiple printk()s per error, we want to be building up a single error message in a printbuf, so that it can be printed with indenting that shows grouping and avoid errors getting interspersed or lost in the log. This gets rid of most calls to bch2_fs_emergency_read_only(). We still have calls to - bch2_fatal_error() - bch2_fs_fatal_error() - bch2_fs_fatal_err_on() that need work.

bcachefs: bch_dev.io_ref -> enumerated_ref

2025-05-22T00:14:28+00:00

Convert device IO refs to enumerated_refs, for easier debugging of refcount issues. Simple conversion: enumerate all users and convert to the new helpers. Signed-off-by: Kent Overstreet

bcachefs: Implement blk_holder_ops

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

We can't use the standard fs_holder_ops because they're meant for single device filesystems - fs_bdev_mark_dead() in particular - and they assume that the blk_holder is the super_block, which also doesn't work for a multi device filesystem. These generally follow the standard fs_holder_ops; the locking/refcounting is a bit simplified because c->ro_ref suffices, and bch2_fs_bdev_mark_dead() is not necessarily shutting down the entire filesystem.

bcachefs: fix deadlock in journal_entry_open()

2025-02-07T03:35:11+00:00

In the previous commit b3d82c2f2761, code was added to prevent journal sequence overflow. Among them, the code added to journal_entry_open() uses the bch2_fs_fatal_err_on() function to handle errors. However, __journal_res_get() , which calls journal_entry_open() , calls journal_entry_open() while holding journal->lock , but bch2_fs_fatal_err_on() internally tries to acquire journal->lock , which results in a deadlock. So we need to add a locked helper to handle fatal errors even when the journal->lock is held.

bcachefs: Kill BCH_TRANS_COMMIT_lazy_rw

2024-12-21T06:36:16+00:00

We unconditionally go read-write, if we're going to do so, before journal replay: lazy_rw is obsolete. Signed-off-by: Kent Overstreet

bcachefs: convert bch_fs_flags to x-macro

2024-01-01T16:47:38+00:00

Now we can print out filesystem flags in sysfs, useful for debugging various "what's my filesystem doing" issues. Signed-off-by: Kent Overstreet
