2021-05-04libceph: allow addrvecs with a single NONE/blank addressIlya Dryomov
Normally, an unused OSD id/slot is represented by an empty addrvec. However, it also appears to be possible to generate an osdmap where an unused OSD id/slot has an addrvec with a single blank address of type NONE. Allow such addrvecs and make the end result be exactly the same as for the empty addrvec case -- leave addr intact.

2021-05-03docs: reporting-issues.rst: CC subsystem and maintainers on regressionsThorsten Leemhuis
When reporting a regression, users ideally should CC the subsystem and its maintainers, as that will ensure they get aware of the regression quickly. And if the culprit is known, they should also CC everyone who signed if off; the text mentioned the latter in once place already, but forgot to do so in two other areas where it's relevant. While fixing this also remind readers to check the mailing list archives for issues that need to be reported to a bug tracker, as someone might have reported it by mail only. All of this got triggered by a recent report where these changes would have made a difference.

2021-05-03ktest: Re-arrange the code blocks for better discoverabilityJohn 'Warthog9' Hawley (VMware)
Perl, as with most scripting languages, is fairly flexible in how / where you can define things, and it will (for the most part) do what you would expect it to do. This however can lead to situations, like with ktest, where things get muddled over time. This pushes the variable definitions back up to the top, followed by functions, with the main script executables down at the bottom, INSTEAD of being somewhat mish-mashed together in certain places. This mostly has the advantage of making it more obvious where things are initially defined, what functions are there, and ACTUALLY where the main script starts executing, and should make this a little more approachable.

2021-05-03ktest: Fixing indentation to match expected patternJohn 'Warthog9' Hawley (VMware)
This is a followup to "ktest: Adding editor hints to improve consistency" to actually adjust the existing indentation to match the, now, expected pattern (first column 4 spaces, 2nd tab, 3rd tab + 4 spaces, etc). This should, at least help, keep things consistent going forward now.

2021-05-03ktest: Adding editor hints to improve consistencyJohn 'Warthog9' Hawley (VMware)
Emacs and Vi(m) have different styles of dealing with perl syntax which can lead to slightly inconsistent indentation, and makes the code slightly harder to read. Emacs assumes a more perl recommended standard of 4 spaces (1 column) or tab (two column) indentation. Vi(m) tends to favor just normal spaces or tabs depending on what was being used. This gives the basic hinting to Emacs and Vim to do what is expected to be basically consistent. Emacs: - Explicitly flip into perl mode, cperl would require more adjustments Vi(m): - Set softtabs=4 which will flip it over to doing indentation the way you would expect from Emacs Signed-off-by: John 'Warthog9' Hawley (VMware) <warthog9@eaglescrag.net> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "New feature: - A new "func-no-repeats" option in tracefs/options directory. When set the function tracer will detect if the current function being traced is the same as the previous one, and instead of recording it, it will keep track of the number of times that the function is repeated in a row. And when another function is recorded, it will write a new event that shows the function that repeated, the number of times it repeated and the time stamp of when the last repeated function occurred. Enhancements: - In order to implement the above "func-no-repeats" option, the ring buffer timestamp can now give the accurate timestamp of the event as it is being recorded, instead of having to record an absolute timestamp for all events. This helps the histogram code which no longer needs to waste ring buffer space. - New validation logic to make sure all trace events that access dereferenced pointers do so in a safe way, and will warn otherwise. Fixes: - No longer limit the PIDs of tasks that are recorded for "saved_cmdlines" to PID_MAX_DEFAULT (32768), as systemd now allows for a much larger range. This caused the mapping of PIDs to the task names to be dropped for all tasks with a PID greater than 32768. - Change trace_clock_global() to never block. This caused a deadlock.

2021-05-03PCI: brcmstb: Use reset/rearm instead of deassert/assertJim Quinlan
The Broadcom STB PCIe RC uses a reset control "rescal" for certain chips. The "rescal" implements a "pulse reset" so using assert/deassert is wrong for this device. Instead, we use reset/rearm. We need to use rearm so that we can reset it after a suspend/resume cycle; w/o using "rearm", the "rescal" device will only ever fire once. Of course for suspend/resume to work we also need to put the reset/rearm calls in the suspend and resume routines.

2021-05-03ata: ahci_brcm: Fix use of BCM7216 reset controllerJim Quinlan
This driver may use one of two resets controllers. Keep them in separate variables to keep things simple. The reset controller "rescal" is shared between the AHCI driver and the PCIe driver for the BrcmSTB 7216 chip. Use devm_reset_control_get_optional_shared() to handle this sharing.

2021-05-03cifs: use echo_interval even when connection not ready.Shyam Prasad N
When the tcp connection is not ready to send requests, we keep retrying echo with an interval of zero. This seems unnecessary, and this fix changes the interval between echoes to what is specified as echo_interval.

2021-05-03cifs: detect dead connections only when echoes are enabled.Shyam Prasad N
We can detect server unresponsiveness only if echoes are enabled. Echoes can be disabled under two scenarios: 1. The connection is low on credits, so we've disabled echoes/oplocks. 2. The connection has not seen any request till now (other than negotiate/sess-setup), which is when we enable these two, based on the credits available. So this fix will check for dead connection, only when echo is enabled.
