Pull ksmbd server fixes from Steve French: - seek null check (don't use f_seek op directly and blindly) - offset validation in FSCTL_SET_ZERO_DATA - fallocate fix (relates e.g. to xfstests generic/091 and 263) - two cleanup fixes - fix socket settings on some arch * tag '5.19-rc4-ksmbd-server-fixes' of git://git.samba.org/ksmbd: ksmbd: use vfs_llseek instead of dereferencing NULL ksmbd: check invalid FileOffset and BeyondFinalZero in FSCTL_ZERO_DATA ksmbd: set the range of bytes to zero without extending file size in FSCTL_ZERO_DATA ksmbd: remove duplicate flag set in smb2_write ksmbd: smbd: Remove useless license text when SPDX-License-Identifier is already used ksmbd: use SOCK_NONBLOCK type for kernel_accept()

MQ version of the deadline IO scheduler.

tristate "Kyber I/O scheduler"
default y
help
The Kyber I/O scheduler is a low-overhead scheduler suitable for
multiqueue and other fast devices. Given target latencies for reads and
synchronous writes, it will self-tune queue depths to achieve that
goal.

help
BFQ I/O scheduler for BLK-MQ. BFQ distributes the bandwidth of
of the device among all processes according to their weights,
regardless of the device parameters and with any workload. It
also guarantees a low latency to interactive and soft
real-time applications. Details in

help
Enable some debugging help. Currently it exports additional stat
files in a cgroup which can be useful for debugging.
