Changes to individual pages
---------------------------
+dup.2
+ Michael Kerrisk
+ Rewrite the description of dup() somewhat
+ As can be seen by any number of StackOverflow questions, people
+ persistently misunderstand what dup() does, and the existing manual
+ page text, which talks of "copying" a file descriptor doesn't help.
+ Rewrite the text a little to try to prevent some of these
+ misunderstandings, in particular noting at the start that dup()
+ allocates a new file descriptor.
+ Michael Kerrisk
+ Clarify what silent closing means
+ Alejandro Colomar
+ SYNOPSIS: Use consistent comments through pages
+
+epoll_wait.2
+ Alejandro Colomar
+ Move misplaced subsection to NOTES from BUGS

+ Michael Kerrisk
+ Library support has been added in glibc 2.34
+
+_exit.2
+ Michael Kerrisk
+ Add a little more detail on the raw _exit() system cal
+
+exit_group.2
+ Alejandro Colomar
+ Use 'noreturn' in prototypes
+
+flock.2
+ Aurelien Aptel [Alejandro Colomar]
+ Add CIFS details
+ CIFS flock() locks behave differently than the standard.
+ Give an overview of those differences.
+
+ioperm.2
+ Alejandro Colomar
+ Remove obvious comment
+
+memfd_create.2
+mmap.2
+shmget.2
+ Michael Kerrisk [Yang Xu]
+ Document the EPERM error for huge page allocations
+ This error can occur if the caller is does not have CAP_IPC_LOCK
+ and is not a member of the sysctl_hugetlb_shm_group.
+
+mmap.2
+ Bruce Merry
+ Clarify that MAP_POPULATE is best-effort
+
+mount.2
+ Topi Miettinen
+ Document SELinux use of MS_NOSUID mount flag
+
+open.2
+ Alejandro Colomar [Walter Harms]
+ Fix bug in linkat(2) call example
+ AT_EMPTY_PATH works with empty strings (""), but not with NULL
+ (or at least it's not obvious).
+ Michael Kerrisk
+ Make it clearer that an FD is an index into the process's FD table
+ Sometimes people are confused, thinking a file descriptor is just a
+ number....
+
+perfmonctl.2
+ Michael Kerrisk
+ This system call was removed in Linux 5.10
+
+pipe.2
+ Alejandro Colomar
+ SYNOPSIS: Fix incorrect prototype

+ (No content changes.)
+ Michael Kerrisk
+ SEE ALSO: add seccomp_unotify(2)
+
+select.2
+ Michael Kerrisk
+ Strengthen the warning regarding the low value of FD_SETSIZE
+ All modern code should avoid select(2) in favor of poll(2)
+ or epoll(7).
+ Michael Kerrisk
+ Relocate sentence about the fd_set value-result arguments to BUGS
+
+syscalls.2
+ Michael Kerrisk
+ perfmonctl(2) was removed in Linux 5.10
+
+bswap.3
+ Alejandro Colomar
+ bswap_*() are implemented using functions
+ Even though it's true that they are macros,
+ it's transparent to the user.
+
+ The user will see their results casted to unsigned types
+ after the conversion due to the underlying functions,
+ so it's better to document these as the underlying functions,
+ specifying the types.
+
+cmsg.3
+unix.7
+ Michael Kerrisk
+ Refer to seccomp_unotify(2) for an example of SCM_RIGHTS usage
+
+cpow.3

+ image, not "the environment of the caller".
+
+fflush.3
+ Alejandro Colomar
+ SEE ALSO: Add fpurge(3)
+
+getline.3
+ наб [Ahelenia Ziemiańska, Alejandro Colomar]

+ a new buffer.

+getopt.3
+ James O. D. Hunt [Alejandro Colomar]
+ Clarify behaviour
+
+printf.3
+ Utkarsh Singh [Alejandro Colomar]

+
+pthread_mutexattr_setrobust.3
+ Michael Kerrisk
+ Note that the *_np() APIs are deprecated since glibc 2.34
+ Alejandro Colomar
+ SYNOPSIS: Remove incorrect 'const'
+
+pthread_mutex_consistent.3

+ Remove obsolete admonishment of the GZIP environment variable
+
+kernel_lockdown.7
+ dann frazier [Alejandro Colomar]
+ Remove description of lifting via SysRq (not upstream)
+ The patch that implemented lockdown lifting via SysRq ended up
+ getting dropped[*] before the feature was merged upstream. Having
+ the feature documented but unsupported has caused some confusion
+ for our users.
+
+mount_namespaces.7
+namespaces.7
+ Michael Kerrisk
+ Relocate reference to pam_namespace(8) from namespaces.7 to
+ mount_namespaces.7.
+
+signal.7
+ Michael Kerrisk
+ Add reference to seccomp_unotify(2)
+ The seccomp user-space notification feature can cause changes in
+ the semantics of SA_RESTART with respect to system calls that
+ would never normally be restarted. Point the reader to the page
+ that provide further details.
+
+vsock.7
+ Alyssa Ross
+ ioctls are on /dev/vsock, not sockets
