2021-11-02io-wq: fix max-workers not correctly set on multi-node systemBeld Zhang
In io-wq.c:io_wq_max_workers(), new_count[] was changed right after each node's value was set. This caused the following node getting the setting of the previous one. Returned values are copied from node 0. Fixes: 2e480058ddc2 ("io-wq: provide a way to limit max number of workers") Signed-off-by: Beld Zhang <beldzhang@gmail.com> [axboe: minor fixups] Signed-off-by: Jens Axboe <axboe@kernel.dk>

2021-11-02cifs: add mount parameter tcpnodelaySteve French
Although corking and uncorking the socket (which cifs.ko already does) should usually have the desired benefit, using the new tcpnodelay mount option causes tcp_sock_set_nodelay() to be set on the socket which may be useful in order to ensure that we don't ever have cases where the network stack is waiting on sending an SMB request until multiple SMB requests have been added to the send queue (since this could lead to long latencies). To enable it simply append "tcpnodelay" it to the mount options Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com>

We generally rely on a bunch of factors to differentiate between servers. For example, IP address, port etc. For certain server types (like Azure), it is important to make sure that the server hostname matches too, even if the both hostnames currently resolve to the same IP address.

commit b1a811633f73 ("block: nbd: add sanity check for first_minor") checks that 'first_minor' should not be greater than 0xff, which is wrong. Whitout the commit, the details that when user pass 0x100000, it ends up create sysfs dir "/sys/block/43:0" are as follows: nbd_dev_add disk->first_minor = index << part_shift -> default part_shift is 5, first_minor is 0x2000000 device_add_disk ddev->devt = MKDEV(disk->major, disk->first_minor) -> (0x2b << 20) | (0x2000000) = 0x2b00000 device_add device_create_sys_dev_entry format_dev_t sprintf(buffer, "%u:%u", MAJOR(dev), MINOR(dev)); -> got 43:0 sysfs_create_link -> /sys/block/43:0 By the way, with the wrong fix, when part_shift is the default value, only 8 ndb devices can be created since 8 << 5 is greater than 0xff. Since the max bits for 'first_minor' should be the same as what MKDEV() does, which is 20. Change the upper bound of 'first_minor' from 0xff to 0xfffff.

2021-11-02drm/i915/adlp/fb: Remove restriction on CCS AUX plane stridesImre Deak
As opposed to other GEN12 platforms ADLP provides a way to program the stride of CCS surfaces independently of the main surface stride (within the corresponding limit of the preceding and succeeding power-of-two values of the main surface stride). Using this HW feature we can remove the POT stride restriction on CCS surfaces, making the ADLP CCS FB uAPI (FB modifiers) identical to that of TGL. The HW makes the CCS stride flexible programming possible by deriving the stride from the value programmed to the PLANE_STRIDE register. After that the HW rounds up this value to the next power-of-two value and uses this for walking the pages of the main surface mapped to GTT/DPT. To align with the above scheme, introduce a scanout_stride view parameter which will be programmed to the PLANE_STRIDE register and use the mapping_stride view param to store the POT aligned value of the same. By requiring userspace to pass in FBs with a CCS stride that aligns with the main surface stride (matching the requirement of all GEN12 platforms), the scanout_stride will be the userspace main surface stride and the mapping_stride will be the POT rounded value of the same.

2021-11-02drm/i915/adlp/fb: Fix remapping of linear CCS AUX surfacesImre Deak
During remapping CCS FBs the CCS AUX surface mapped size and offset->x,y coordinate calculations assumed a tiled layout. This works as long as the CCS surface height is aligned to 64 lines (ensuring a 4k bytes CCS surface tile layout). However this alignment is not required by the HW (and the driver doesn't enforces it either). Add the remapping logic required to remap the pages of CCS surfaces without the above alignment, assuming the natural linear layout of the CCS surface (vs. tiled main surface layout).

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 core updates from Borislav Petkov: - Do not #GP on userspace use of CLI/STI but pretend it was a NOP to keep old userspace from breaking. Adjust the corresponding iopl selftest to that. - Improve stack overflow warnings to say which stack got overflowed and raise the exception stack sizes to 2 pages since overflowing the single page of exception stack is very easy to do nowadays with all the tracing machinery enabled. With that, rip out the custom mapping of AMD SEV's too. - A bunch of changes in preparation for FGKASLR like supporting more than 64K section headers in the relocs tool, correct ORC lookup table size to cover the whole kernel .text and other adjustments. * tag 'x86_core_for_v5.16_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: selftests/x86/iopl: Adjust to the faked iopl CLI/STI usage vmlinux.lds.h: Have ORC lookup cover entire _etext - _stext x86/boot/compressed: Avoid duplicate malloc() implementations x86/boot: Allow a "silent" kaslr random byte fetch x86/tools/relocs: Support >64K section headers x86/sev: Make the #VC exception stacks part of the default stacks storage x86: Increase exception stack sizes x86/mm/64: Improve stack overflow warnings x86/iopl: Fake iopl(3) CLI/STI usage
2021-11-02dm: don't stop request queue after the dm device is suspendedMing Lei
For fixing queue quiesce race between driver and block layer(elevator switch, update nr_requests, ...), we need to support concurrent quiesce and unquiesce, which requires the two call to be balanced. __bind() is only called from dm_swap_table() in which dm device has been suspended already, so not necessary to stop queue again. With this way, request queue quiesce and unquiesce can be balanced.

2021-11-02i915/display/dp: send a more fine-grained link-status ueventSimon Ser
When link-status changes, send a hotplug uevent which contains the connector ID. That way, user-space can more easily figure out that only this connector has been updated.
