- Some tweaks to greatly reduce locking overhead for the list of btree transactions, so that it can always be enabled: leave btree_trans objects on the list when they're on the percpu single item freelist, and only check for duplicates in the same process when CONFIG_BCACHEFS_DEBUG is enabled - don't zero out the full btree_trans() unless we allocated it from the mempool Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
