Commit f4af6bb783 which added support
for REQ_FAILFAST_MASK but the new autoconf test didn't use the same
preprocessor macro name as the code did.
The effect is that FAILFAST mode has not been enabled for ZoL in any
post-2.6.35 kernel.
Retire the HAVE_BIO_RW_FAILFAST interface used in pre-2.6.28 kernels.
Raise an error condition if the FAILFAST interface can't be detected.

This commit updates the copyright boilerplate within the ZED subtree.
The instructions for appending a contributor copyright line have
been removed. Manually maintaining copyright notices in this
manner is error-prone, imprecise at a file-scope granularity, and
oftentimes inaccurate. These lines can become a pernicious source of
merge conflicts. A commit log is better suited to maintaining this
information. Consequently, a line has been added to the boilerplate
to refer to the git commit log for authoritative copyright attribution.
To account for the scenario where a file may become separated from
the codebase and commit history (i.e., it is copied somewhere else),
a line has been added to identify the file's origin.

The security and ACL operations should all be performed atomically.
To accomplish this there would need to significant invasive changes

Porting Notes:
* Included in this patch is a tiny ISP2() cleanup in zio_init() from
Illumos 5255.
* Unlike the upstream Illumos commit this patch does not impose an
arbitrary 128K block size limit on volumes. Volumes, like filesystems,
are limited by the zfs_max_recordsize=1M module option.
* By default the maximum record size is limited to 1M by the module
option zfs_max_recordsize. This value may be safely increased up to
16M which is the largest block size supported by the on-disk format.
At the moment, 1M blocks clearly offer a significant performance
improvement but the benefits of going beyond this for the majority
of workloads are less clear.
* The illumos version of this patch increased DMU_MAX_ACCESS to 32M.
This was determined not to be large enough when using 16M blocks
because the zfs_make_xattrdir() function will fail (EFBIG) when
assigning a TX. This was immediately observed under Linux because
all newly created files must have a security xattr created and
that was failing. Therefore, we've set DMU_MAX_ACCESS to 64M.
* On 32-bit platforms a hard limit of 1M is set for blocks due
to the limited virtual address space. We should be able to relax
this one the ABD patches are merged.

The umem_alloc_aligned() function should not assume that a 'void *'
type is 64-bit. It will not be on 32-bit platforms. Rather than
complicating the ASSERT to handle this it is simply removed.
Additionally, the '%lu' format specifier should not be assumed to
imply a 64-bit value. Fix this by using the 'llu' format specifier
which will always be atleast 64-bit and explicitly casing the
variable to an u_longlong_t. This issue is handled the same way
in many other parts of the code.

It's been reported that threads would loop infinitely inside zfs_zget. The
speculated cause for this is that if an inode is marked for evict, zfs_zget
would see that and loop. However, if the looping thread doesn't yield, the
inode may not have a chance to finish evict, thus causing a infinite loop.
This patch solve this issue by add cond_resched to zfs_zget, making the
looping thread to yield when needed.

In traverse_visitbp(), the input argument dnp is modified in the middle to
point to a temporary buffer. Originally this doesn't matter, because no user
of TRAVERSE_POST dereferences it. However, in fbeddd6 a piece of code is added
dereferencing dnp after the modification, creating a possible bug.
We fix this by creating a new local variable cdnp for the DMU_OT_DNODE case,
so we don't modify the input argument. Also we introduce different local
variables in the DMU_OT_OBJSET case to prevent confusion between the input
argument.

This patch stack begins with cleaning up the existing ZEDLETs,
refactoring common code blocks into zed-functions.sh, adopting a

now run cleanly through ShellCheck.
The old "email" ZEDLETs are replaced with new "notify" ZEDLETs. A
notification can now be sent via email and/or Pushbullet. Additional
notification methods will likely be added in the future.
Pushbullet notifications are enabled by setting the
ZED_PUSHBULLET_ACCESS_TOKEN and (optionally) ZED_PUSHBULLET_CHANNEL_TAG
in zed.rc. The Pushbullet implementation requires awk, curl, and sed

The data-notify.sh ZEDLET serves a very similar purpose to
io-notify.sh, namely, to generate a notification in response to a
particular error event. Initially, data-notify.sh was separated from
io-notify.sh since the "data" zevent does not (as I understand it)
pertain to a specific vdev device. This stands in contrast to the
"checksum" and "io" zevents (both handled by io-notify.sh) that can
be attributed to a specific vdev. At the time, it seemed simpler to
handle these two cases in separate scripts.
This commit adds support for the "data" zevent to io-notify.sh, and
symlinks io-notify.sh to data-notify.sh. It also adds the counts
for vdev_read_errors, vdev_write_errors, and vdev_cksum_errors to
the notification message.

replaced with a hot spare after encountering a checksum or io error.

This commit adds the zed_notify_pushbullet() function and hooks
it into zed_notify(), thereby integrating it with the existing
"notify" ZEDLETs. This enables ZED to push notifications to your
desktop computer and/or mobile device(s). It is configured with the
ZED_PUSHBULLET_ACCESS_TOKEN and ZED_PUSHBULLET_CHANNEL_TAG variables
in zed.rc.
https://www.pushbullet.com/
The Makefile install-data-local target has been replaced with
install-data-hook. With the "-local" target, there is no particular
guarantee of execution order. But with the zed.rc now potentially
containing sensitive information (i.e., the Pushbullet access token),
the recommended permissions have changed to 0600. The "-hook" target
is always executed after the main rule's work is done; thus, the
chmod will always take place after the zed.rc file has been installed.

Several ZEDLETs already exist for sending email in reponse to a
particular zevent. While email is ubiquitous, alternative methods may
be better suited for some configurations. Instead of duplicating the
"email" ZEDLETs for every future notification method, it is preferable
to abstract the notification method into a function. This has the
added benefit of reducing the amount of code duplicated between
ZEDLETs, and allowing related bugs to be fixed in a single location.
This commit replaces the existing "email" ZEDLETs with corresponding
"notify" ZEDLETs. In addition, the ZEDLET code for sending an
email message has been moved into the zed_notify_email() function.
And this zed_notify_email() has been added to a generic zed_notify()
function for sending notifications via all available methods that
have been configured.
This commit also changes a couple of related zed.rc variables.
ZED_EMAIL_INTERVAL_SECS is changed to ZED_NOTIFY_INTERVAL_SECS,
and ZED_EMAIL_VERBOSE is changed to ZED_NOTIFY_VERBOSE. Note that
ZED_EMAIL remains unchanged as its use is solely for the email
notification method.

This commit factors out several common ZEDLET code blocks into

In addition, this commit revamps the coding style used by the

It now mostly follows the Google Shell Style Guide. I've tried to
