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: Kill btree_iter.trans

2025-04-02T14:24:34+00:00

This was planned to be done ages ago, now finally completed; there are places where we have quite a few btree_trans objects on the stack, so this reduces stack usage somewhat. Signed-off-by: Kent Overstreet

bcachefs: Use FOREACH_ACL_ENTRY() macro to iterate over acl entries

2024-12-21T06:36:14+00:00

Use the existing FOREACH_ACL_ENTRY() macro to iterate over POSIX acl entries and remove the custom acl_for_each_entry() macro. Signed-off-by: Thorsten Blum Signed-off-by: Kent Overstreet

bcachefs: switch to rhashtable for vfs inodes hash

2024-09-09T13:41:47+00:00

the standard vfs inode hash table suffers from painful lock contention - this is long overdue Signed-off-by: Kent Overstreet

bcachefs: Switch to .get_inode_acl()

2024-08-08T19:14:02+00:00

.set_acl() requires a dentry, and if one isn't passed it marks the VFS inode as not having an ACL. This has been causing inodes with ACLs to have them "disappear" on bcachefs filesystem, depending on which path those inodes get pulled into the cache from. Switching to .get_inode_acl(), like other local filesystems, fixes this. Signed-off-by: Kent Overstreet

bcachefs: fix ei_update_lock lock ordering

2024-07-14T23:00:11+00:00

ei_update_lock is largely vestigal and will probably be removed, but we're not ready for that just yet. this fixes some lockdep splats with the new lockdep support for btree node locks; they're harmless, since we were taking ei_update_lock before actually locking any btree nodes, but "any btree nodes locked" are now tracked at the btree_trans level.

bcachefs: iter/update/trigger/str_hash flag cleanup

2024-05-08T21:29:18+00:00

Combine iter/update/trigger/str_hash flags into a single enum, and x-macroize them for a to_text() function later. These flags are all for a specific iter/key/update context, so it makes sense to group them together - iter/update/trigger flags were already given distinct bits, this cleans up and unifies that handling.

bcachefs: bch2_hash_lookup() now returns bkey_s_c

2024-05-08T21:29:17+00:00

small cleanup Signed-off-by: Kent Overstreet

bcachefs: fix bch2_get_acl() transaction restart handling

2024-04-07T21:15:53+00:00

bch2_acl_from_disk() uses allocate_dropping_locks, and can thus return a transaction restart - this wasn't handled. Signed-off-by: Kent Overstreet

bcachefs: make RO snapshots actually RO

2024-01-01T16:47:07+00:00

Add checks to all the VFS paths for "are we in a RO snapshot?". Note - we don't check this when setting inode options via our xattr interface, since those generally only affect data placement, not contents of data. Signed-off-by: Kent Overstreet Reported-by: "Carl E. Thompson"
