What were you trying to do that didn't work?

There are some syscalls without manpages.

Regarding the list of syscalls found in /usr/src/kernels/5.14.0-284.30.1.el9_2.x86_64/tools/include/uapi/asm-generic/unistd.h:

Those syscalls don't have a manpage, whereas we can see it in https://man7.org/linux/man-pages/man2/:

• io_uring_setup
• io_uring_enter
• io_uring_register
• close_range
• process_madvise
• epoll_pwait2
• mount_setattr
• landlock_create_ruleset
• landlock_add_rule
• landlock_restrict_self
• memfd_secret

Those syscalls seems not to have manpages on the site "man7.org" but for some of them, I found commits proposing content. I don't know if those commits have been accepted or not:

• io_pgetevents
• rseq
• clock_gettime64
• clock_settime64
• clock_adjtime64
• clock_getres_time64
• clock_nanosleep_time64
• timer_gettime64
• timer_settime64
• timerfd_gettime64
• timerfd_settime64
• utimensat_time64
• pselect6_time64
• ppoll_time64
• io_pgetevents_time64
• recvmmsg_time64
• mq_timedsend_time64
• mq_timedreceive_time64
• semtimedop_time64
• rt_sigtimedwait_time64
• futex_time64
• sched_rr_get_interval_time64
• open_tree
• move_mount
• fsopen
• fsconfig
• fsmount
• fspick
• quotactl_fd
• futex_waitv

Can you add the missing manpages?
