+Subject: [PATCH] deadlock between mm_sem and tx assign in zfs_write() and page
+ fault
+
+The bug time sequence:
+1. thread #1, `zfs_write` assign a txg "n".
+2. In a same process, thread #2, mmap page fault (which means the
+   `mm_sem` is hold) occurred, `zfs_dirty_inode` open a txg failed,
+   and wait previous txg "n" completed.
+3. thread #1 call `uiomove` to write, however page fault is occurred
+   in `uiomove`, which means it need `mm_sem`, but `mm_sem` is hold by
+   thread #2, so it stuck and can't complete,  then txg "n" will
+   not complete.
+
+So thread #1 and thread #2 are deadlocked.

+Subject: [PATCH] Fix deadlock between zfs umount & snapentry_expire
+
+zfs umount -> zfsctl_destroy() takes the zfs_snapshot_lock as a
+writer and calls zfsctl_snapshot_unmount_cancel(), which waits
+for snapentry_expire() if present (when snap is automounted).
+This snapentry_expire() itself then waits for zfs_snapshot_lock
+as a reader, resulting in a deadlock.
+
+The fix is to only hold the zfs_snapshot_lock over the tree
+lookup and removal.  After a successful lookup the lock can
+be dropped and zfs_snapentry_t will remain valid until the
+reference taken by the lookup is released.

+Subject: [PATCH] Fix race in dnode_check_slots_free()
+
+Currently, dnode_check_slots_free() works by checking dn->dn_type
+in the dnode to determine if the dnode is reclaimable. However,
+there is a small window of time between dnode_free_sync() in the
+first call to dsl_dataset_sync() and when the useraccounting code
+is run when the type is set DMU_OT_NONE, but the dnode is not yet
+evictable, leading to crashes. This patch adds the ability for
+dnodes to track which txg they were last dirtied in and adds a
+check for this before performing the reclaim.
+
+This patch also corrects several instances when dn_dirty_link was
+treated as a list_node_t when it is technically a multilist_node_t.

+Subject: [PATCH] Reduce taskq and context-switch cost of zio pipe
+
+When doing a read from disk, ZFS creates 3 ZIO's: a zio_null(), the
+logical zio_read(), and then a physical zio. Currently, each of these
+results in a separate taskq_dispatch(zio_execute).
+
+On high-read-iops workloads, this causes a significant performance
+impact. By processing all 3 ZIO's in a single taskq entry, we reduce the
+overhead on taskq locking and context switching.  We accomplish this by
+allowing zio_done() to return a "next zio to execute" to zio_execute().
+
+This results in a ~12% performance increase for random reads, from
+96,000 iops to 108,000 iops (with recordsize=8k, on SSD's).

+Subject: [PATCH] deadlock between mm_sem and tx assign in zfs_write() and page
+ fault
+
+The bug time sequence:
+1. thread #1, `zfs_write` assign a txg "n".
+2. In a same process, thread #2, mmap page fault (which means the
+   `mm_sem` is hold) occurred, `zfs_dirty_inode` open a txg failed,
+   and wait previous txg "n" completed.
+3. thread #1 call `uiomove` to write, however page fault is occurred
+   in `uiomove`, which means it need `mm_sem`, but `mm_sem` is hold by
+   thread #2, so it stuck and can't complete,  then txg "n" will
+   not complete.
+
+So thread #1 and thread #2 are deadlocked.
