* x86/mce: Remove the tolerance level controlBorislav Petkov2022-02-231-32/+0
| | | | | | | | | | | | This is pretty much unused and not really useful. What is more, all relevant MCA hardware has recoverable machine checks support so there's no real need to tweak MCA tolerance levels in order to *maybe* extend machine lifetime. So rip it out.

| * f2fs: add gc_urgent_high_remaining sysfs nodeDaeho Jeong2021-12-101-0/+7
| | | | | | | | | | | | | | | | | | | | Added a new sysfs node called gc_urgent_high_remaining. The user can set the trial count limit for GC urgent high mode with this value. If GC thread gets to the limit, the mode will turn back to GC normal mode. By default, the value is zero, which means there is no limit like before.

If `driver_override` is not set, the previous behaviour is followed: devices use the first vDPA bus driver loaded (unless auto binding is disabled). Tested on Fedora 34 with driverctl(8): $ modprobe virtio-vdpa $ modprobe vhost-vdpa $ modprobe vdpa-sim-net $ vdpa dev add mgmtdev vdpasim_net name dev1 # dev1 is attached to the first vDPA bus driver loaded $ driverctl -b vdpa list-devices dev1 virtio_vdpa $ driverctl -b vdpa set-override dev1 vhost_vdpa $ driverctl -b vdpa list-devices dev1 vhost_vdpa [*] Note: driverctl(8) integrates with udev so the binding is preserved.

A small additional set of things that just missed the previous pull request and have mostly been through plenty of review before the holiday period began (or are trivial). I've not taken some other series on the list to allow for more eyes after the holiday period. New device support * adi,admv1013 - New driver for this wideband microwave upconverter including dt-bindings and some device specific ABI due to the need to describe phase calibrations of a differential channel on both i and q phases. Previously we could do differential or i/q but not both on the same channel. The driver ABI uses a workaround for core support which will do until we know if this is a common requirement for which a more generic solution is needed. MAINTAINERS: * Add Haibo Chen as a maintainer for various NXP SoC ADCs. Minor cleanup: * sunrise_co2 - Make sure an uninitialized value isn't used to set *val in read_raw(). Not a real bug, but a compiler or reviewer can't tell that based on what they can see locally. * tag 'iio-for-5.17b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: iio: chemical: sunrise_co2: set val parameter only on success dt-bindings:iio:adc: update the maintainer of vf610-adc MAINTAINERS: add imx7d/imx6sx/imx6ul/imx8qxp and vf610 adc maintainer Documentation:ABI:testing:admv1013: add ABI docs dt-bindings: iio: frequency: add admv1013 doc iio: frequency: admv1013: add support for ADMV1013

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added two options into "mode=" mount option to make it possible for developers to simulate filesystem fragmentation/after-GC situation itself. The developers use these modes to understand filesystem fragmentation/after-GC condition well, and eventually get some insights to handle them better. "fragment:segment": f2fs allocates a new segment in ramdom position. With this, we can simulate the after-GC condition. "fragment:block" : We can scatter block allocation with "max_fragment_chunk" and "max_fragment_hole" sysfs nodes. f2fs will allocate 1..<max_fragment_chunk> blocks in a chunk and make a hole in the length of 1..<max_fragment_hole> by turns in a newly allocated free segment. Plus, this mode implicitly enables "fragment:segment" option for more randomness.
