This field is used only by illumos mdb. On other platforms it only increases the struct size from 32 to 40 bytes. For struct vdev_queue including 13 instances of avl_tree_t size means active cache lines. Keep the padding in user-space for now to not break the ABI.

| 490c845e | noreply | July 1, 2021, 3:30 p.m. | Compact dbuf/buf hashes and lock arrays
With default dbuf cache size of 1/32 of ARC, it makes no sense to have hash table of the same size (or even bigger on Linux). Reduce it to 1/8 of ARC's one, still leaving some slack, assuming higher I/O rate via dbuf cache than via ARC. Remove padding from ARC hash locks array. The idea behind padding is to avoid false sharing between locks. It would have sense if there would be a limited number of very busy locks. But since we have no limit on the number, using the same memory for more locks we can achieve even lower lock contention with the same false sharing, or we can use less memory for the same contention level. Reduce number of hash locks from 8192 to 2048. The number is still big enough to not cause contention, but reduced memory size improves cache hit rate for mutex_tryenter() in ARC eviction thread, saving about 1% of the thread time.

Fix a leak of abd_t that manifested mostly when using raidzN with at least as many columns as N (e.g. a four-disk raidz2 but not a three-disk raidz2). Sufficiently heavy raidz use would eventually run a system out of memory. Additionally: * Switch abd_cache arena to FIRSTFIT, which empirically improves perofrmance. * Make abd_chunk_cache more performant and debuggable. * Allocate the abd_zero_buf from abd_chunk_cache rather than the heap. * Don't try to reap non-existent qcaches in abd_cache arena. * KM_PUSHPAGE->KM_SLEEP when allocating chunks from their own arena Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Reviewed-by: Alexander Motin <mav@FreeBSD.org> Signed-off-by: Jorgen Lundman <lundman@lundman.net> Co-authored-by: Sean Doran <smd@use.net> Closes #12295cgit |

Use dp_dirty_pertxg[] for txg_kick(), instead of dp_dirty_total in original code. Extra parameter "txg" is added for txg_kick(), thus it knows which txg to kick. Also txg_kick() call is moved from dsl_pool_need_dirty_delay() to dsl_pool_dirty_space() so that we can know the txg number assigned for txg_kick(). Some unnecessary code regarding dp_dirty_total in txg_sync_thread() is also cleaned up.

The only reason for spa_config_*() to use refcount instead of simple non-atomic (thanks to scl_lock) variable for scl_count is tracking, hard disabled for the last 8 years. Switch to simple int scl_count reduces the lock hold time by avoiding atomic, plus makes structure fit into single cache line, reducing the locks contention.
