While reviewing the LOGO handling a few other issues were seen and
were addressed:
- Better lock synchronization around ndlp data types
- When the ABTS times out, unregister the RPI before sending the LOGO
so that all local exchange contexts are cleared and nothing received
while awaiting LOGO/PLOGI handling will be accepted.
- LOGO handling optimized to:
Wait only R_A_TOV for a response.
It doesn't need to be retried on timeout. If there wasn't a
response, a PLOGI will be sent, thus an implicit logout
applies as well when the other port sees it.
If there is a response, any kind of response is considered "good"
and the XRI quarantined for a exchange qualifier window.
- PLOGI is issued as soon a LOGO state is resolved.

scsi: lpfc: Correct speeds on SFP swap
Supported speeds is not updated when SFP is removed or replaced
Supported speed is obtained from lmt field in READ_CONFIG mailbox
response. Driver updates supported speeds only once from PCI probe
path. After that it is never updated. So, supported speeds remains the
same till reboot or driver reload.
When SFP is removed or inserted, driver gets SLI-Port Event ACQE. If
SFP is removed, lmt wil have value 0. If a different SFP is inserted,
lmt will have value according to its supported speeds. So, afterr
SLI-Port Event ACQE handling path, send READ_CONFIG mailbox and update
supported speeds. If READ_CONFIG fails, set supported speeds to
unknown and log.

scsi: megaraid_sas: Add watchdog thread to detect Firmware fault
Currently driver checks for Firmware state change from ISR context, and
only when there are interrupts tied with no I/O completions. We have seen
multiple cases where doorbell interrupts sent by firmware to indicate FW
state change are not processed by driver and it takes long time for driver
to trigger OCR. And if there are no IOs running, since we only check the FW
state as part of ISR code, fault goes undetected by driver and OCR will not
be triggered.
This patch introduces a separate workqueue that runs every one second to
detect Firmware FAULT state and trigger reset immediately. As an
additional gain, removing PCI reads from ISR to check FW state results in
improved performance as well.

It has been reported on an older (4.12) kernel but the current upstream
code doesn't cond_resched in the hot remove code at all and the given
range to remove might be really large. Fix the issue by calling
cond_resched once per memory section.

bfs: add sanity check at bfs_fill_super()
syzbot is reporting too large memory allocation at bfs_fill_super() [1].
Since file system image is corrupted such that bfs_sb->s_start == 0,
bfs_fill_super() is trying to allocate 8MB of continuous memory. Fix
this by adding a sanity check on bfs_sb->s_start, __GFP_NOWARN and
printf().
