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.

The peek_end() tests expect an empty btree.

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.

bcachefs: Rename btree_iter_peek_upto() -> btree_iter_peek_max()

2024-12-21T06:36:17+00:00

We'll be introducing btree_iter_peek_prev_min(), so rename for
consistency.

bcachefs: check the invalid parameter for perf test

2024-11-07T21:48:21+00:00

The perf_test does not check the number of iterations and threads
when it is zero. If nr_thread is 0, the perf test will keep
waiting for wakekup. If iteration is 0, it will cause exception
of division by zero. This can be reproduced by:
  echo "rand_insert 0 1" > /sys/fs/bcachefs/${uuid}/perf_test
or
  echo "rand_insert 1 0" > /sys/fs/bcachefs/${uuid}/perf_test

bcachefs: Don't use commit_do() unnecessarily

2024-10-18T04:49:48+00:00

Using commit_do() to call alloc_sectors_start_trans() breaks when we're
randomly injecting transaction restarts - the restart in the commit
causes us to leak the lock that alloc_sectorS_start_trans() takes.

bcachefs: bch2_btree_insert() - add btree iter flags

2024-07-14T23:00:15+00:00

The commit 65bd44239727 ("bcachefs: bch2_btree_insert_trans() no longer
specifies BTREE_ITER_cached") removes BTREE_ITER_cached from
bch2_btree_insert_trans, which causes the update_inode function from
bcachefs-tools to take a long time (~20s).  Add an iter_flags parameter
to bch2_btree_insert, so the users can specify iter update trigger
flags, such as BTREE_ITER_cached.

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.
