Due to a possible lock inversion the zvol open call path on Linux
needs to be able to retry in the case where the spa_namespace_lock
cannot be acquired.
For Linux 5.12 an older kernel this was accomplished by returning
-ERESTARTSYS from zvol_open() to request that blkdev_get() drop
the bdev->bd_mutex lock, reaquire it, then call the open callback
again. However, as of the 5.13 kernel this behavior was removed.
Therefore, for 5.12 and older kernels we preserved the existing
retry logic, but for 5.13 and newer kernels we retry internally in
zvol_open(). This should always succeed except in the case where
a pool's vdev are layed on zvols, in which case it may fail. To
handle this case vdev_disk_open() has been updated to retry when
opening a device when -ERESTARTSYS is returned.

Additionally, while not strictly required, the dn_struct_rwlock is

the data/hole is located. The range lock is now also taken to

This apparently works on newer kernels because the caller which breaks
on older Linux kernels by happily passing along a 1M read request and a

this isn't necessarily needed, as we may be able to resolve the dm

A multpathed disk will have several 'underlying' paths to the disk. For
example, multipath disk 'dm-0' may be made up of paths:
/dev/{sda,sdb,sdc,sdd}. On many enclosures those underlying sysfs
paths will have a symlink back to their enclosure device entry
(like 'enclosure_device0/slot1'). This is used by the
statechange-led.sh script to set/clear the fault LED for a disk, and
by 'zpool status -c'.
However, on some enclosures, those underlying paths may not all have
symlinks back to the enclosure device. Maybe only two out of four
of them might.
This patch updates zfs_get_enclosure_sysfs_path() to favor returning
paths that have symlinks back to their enclosure devices, rather

Within function sas_handler() userspace commands like
'/usr/sbin/multipath' have been replaced with sourcing
device details from within sysfs which reduced a
significant amount of overhead and processing time.
Multiple JBOD enclosures and their order are sourced
from the bsg driver (/sys/class/enclosure) to isolate
chassis top-level expanders, which are then dynamically
indexed based on host channel of the multipath subordinate
disk member device being processed. Additionally added a
"mixed" mode for slot identification for environments where
a ZFS server system may contain SAS disk slots where there
is no expander (direct connect to HBA) while an attached
external JBOD with an expander have different slot identifier
methods.
How Has This Been Tested?
~~~~~~~~~~~~~~~~~~~~~~~~~
Testing was performed on a AMD EPYC based dual-server
high-availability multipath environment with multiple
HBAs per ZFS server and four SAS JBODs. The two primary
JBODs were multipath/cross-connected between the two
ZFS-HA servers. The secondary JBODs were daisy-chained
off of the primary JBODs using aligned SAS expander
channels (JBOD-0 expanderA--->JBOD-1 expanderA,
JBOD-0 expanderB--->JBOD-1 expanderB, etc).
Pools were created, exported and re-imported, imported
globally with 'zpool import -a -d /dev/disk/by-vdev'.
Low level udev debug outputs were traced to isolate
and resolve errors.
Result:
~~~~~~~
Initial testing of a previous version of this change
showed how reliance on userspace utilities like
'/usr/sbin/multipath' and '/usr/bin/lsscsi' were
exacerbated by increasing numbers of disks and JBODs.
With four 60-disk SAS JBODs and 240 disks the time to
process a udevadm trigger was 3 minutes 30 seconds
during which nearly all CPU cores were above 80%
utilization. By switching reliance on userspace
utilities to sysfs in this version, the udevadm
trigger processing time was reduced to 12.2 seconds
and negligible CPU load.
This patch also fixes few shellcheck complains.
