When adapting the original sources for s390x the JMP_BUF_CNT was
mistakenly halved due to an incorrect assumption of the size of
a unsigned long.  They are 8 bytes for the s390x architecture.
Increase JMP_BUF_CNT accordingly.

When a system boots the zfs-mount.service and the
zfs-share.service can start simultaneously. What may be
unclear is that sharing a filesystem will first mount
the filesystem if it's not already mounted. This means
that both service can race to mount the same fileystem.
This race can result in a SEGFAULT or EBUSY conditions.

This change explicitly defines the start ordering between the
two services such that the zfs-mount.service is solely
responsible for mounting filesystems eliminating the race
between "zfs mount -a" and "zfs share -a" commands.

nfsstat -s prints bogus large numbers for the Server Re-Failed and Server
Faults fields. This was introduced by r328588.
Although I know nothing about libxo, these lines aren't titles and this
patch seems to fix the problem, so I am committing it for rea@ who emailed
it to me.
It also deleted the trailing ':' from the title lines, since those were not
in the pre-r328588 output.

If there is a more correct fix, someone conversant with libxo will need
to do so.

counter, and the final freeing of freed swap blocks, outside the
region where an object lock is held.  Correct some style(9) and
spelling errors.  Change a panic() to a KASSERT().  Change a boolean_t
to a bool.

When a fusefs file system is mounted using the writeback cache, the cache
may still be bypassed by opening a file with O_DIRECT.  When writing with
O_DIRECT, the cache must be invalidated for the affected portion of the
file.  Fix some panics caused by inadvertently invalidating too much.

v_inval_buf_range invalidates all buffers within a certain LBA range of a
file. It will be used by fusefs(5). This commit is a partial merge of
r346162, r346606, and r346756 from projects/fuse2.
