 block manual building in the dkms source tree.
  To avoid messing up future DKMS builds and the zfs installation,
  block manual building of the DKMS source tree.

 enable zed emails
 The OpenZFS event daemon monitors pools.  This patch enables the email
 sending function by default (if zed is installed).  This is consistent with
 the default behavior of mdadm.

 fix the path to the zed binary on the systemd unit.
 We install zed into /usr/sbin manually meanwhile the upstream default
 is installing it into /sbin.
 Ubuntu packages also install zed to /usr/sbin, but they ship their own
 zfs-zed unit.

 [patch] linux 5.0 compat: disable vector instructions on 5.0+ kernels

The 5.0 kernel no longer exports the functions we need to do vector
(SSE/SSE2/SSE3/AVX...) instructions.  Disable vector-based checksum
algorithms when building against those kernels.

 [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.

 [patch] openzfs 9577 - remove zfs_dbuf_evict_key tsd

The zfs_dbuf_evict_key TSD (thread-specific data) is not necessary -
we can instead pass a flag down in a few places to prevent recursive
dbuf eviction. Making this change has 3 benefits:

1. The code semantics are easier to understand.
2. On Linux, performance is improved, because creating/removing
   TSD values (by setting to NULL vs non-NULL) is expensive, and
   we do it very often.
3. According to Nexenta, the current semantics can cause a
   deadlock when concurrently calling dmu_objset_evict_dbufs()
   (which is rare today, but they are working on a "parallel
   unmount" change that triggers this more easily):

Porting Notes:
* Minor conflict with OpenZFS 9337 which has not yet been ported.
