2021-08-17drm: Copy drm_wait_vblank to user before returningMark Yacoub1-3/+1
[Why] Userspace should get back a copy of drm_wait_vblank that's been modified even when drm_wait_vblank_ioctl returns a failure. Rationale: drm_wait_vblank_ioctl modifies the request and expects the user to read it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates the sequence to become current_vblank_count + sequence (which was RELATIVE), but now it became ABSOLUTE. drmWaitVBlank (in libdrm) expects this to be the case as it modifies the request to be Absolute so it expects the sequence to would have been updated. The change is in compat_drm_wait_vblank, which is called by drm_compat_ioctl. This change of copying the data back regardless of the return number makes it en par with drm_ioctl, which always copies the data before returning. [How] Return from the function after everything has been copied to user.

As follow-up to the discussion with Jakub Kicinski about iavf locking being insufficient [1] convert iavf to use mutexes instead of bitops. The locking logic is kept as is, just a drop-in replacement of enum iavf_critical_section_t with separate mutexes. The only difference is that the mutexes will be destroyed before the module is unloaded.

2021-08-17mtd: mtdconcat: Judge callback existence based on the masterZhihao Cheng1-8/+19
Since commit 46b5889cc2c5("mtd: implement proper partition handling") applied, mtd partition device won't hold some callback functions, such as _block_isbad, _block_markbad, etc. Besides, function mtd_block_isbad() will get mtd device's master mtd device, then invokes master mtd device's callback function. So, following process may result mtd_block_isbad() always return 0, even though mtd device has bad blocks: 1. Split a mtd device into 3 partitions: PA, PB, PC [ Each mtd partition device won't has callback function _block_isbad(). ] 2. Concatenate PA and PB as a new mtd device PN [ mtd_concat_create() finds out each subdev has no callback function _block_isbad(), so PN won't be assigned callback function concat_block_isbad(). ] Then, mtd_block_isbad() checks "!master->_block_isbad" is true, will always return 0.

2021-08-17mtd: rfd_ftl: add discard supportSean Young1-0/+29
I proposed this change 16 years ago before discard was a feature in the block layer: https://lwn.net/Articles/162776/ Now that the block layer has discard, we can finally merge this change. Discard is also known as trim. By implementing discard, both fstrim and the discard filesystem option can be used. Implementing discard in the ftl means that when files are removed, there is less data in the ftl mapping. This means less stuff to move around for erasing and also less erasing to do; this means improved wear levelling and improved performance.

2021-08-17mtdblock: Warn if added for a NAND deviceEzequiel Garcia2-0/+8
There is a surprisingly large number of tutorials that suggest using mtdblock to mount SquashFS filesystems on flash devices, including NAND devices. This approach is suboptimal than using UBI. If the flash device is NAND, this is specially true, due to wear leveling, bit-flips and badblocks. In this case UBI is strongly preferred, so be nice to users and print a warning suggesting to consider UBI block, if mtdblock is added for a NAND device.
