Remove bcachefs core code

2025-09-29T20:43:52Z

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.

Standard inlining of fast paths - these locks are now used by our new nocow mode. Signed-off-by: Kent Overstreet

bcachefs: Factor out two_state_shared_lock

2023-10-22T21:09:45Z

We have a unique lock used for controlling adding to the pagecache: the lock has two states, where both states are shared - the lock may be held multiple times for either state - but not both states at the same time. This is exactly what we need for nocow mode locking, so this patch pulls it out of fs.c into its own file. Signed-off-by: Kent Overstreet
