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 Fixes: 1c6fdbd8f246 ("bcachefs: Initial commit") Signed-off-by: Hongbo Li <lihongbo22@huawei.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> 2024-10-18T04:49:48+00:00 Kent Overstreet kent.overstreet@linux.dev 2024-10-14T01:53:26+00:00 urn:sha1:a0d11feefb1998204f095fa0400024403d233108 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.

Add an iter_flags parameter to bch2_btree_insert, so the users can specify iter update trigger flags, such as BTREE_ITER_cached.

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.

But we have to do a heap allocatation to initialize it anyways, so there's no real downside to heap allocating the entire thing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
