Global changes
--------------
-Various pages
- Alejandro Colomar
- Use ``sizeof`` consistently through all the examples in the
- following way:
-
- - Use the name of the variable instead of its type as argument for
- ``sizeof``.
-
-Various pages
- Alejandro Colomar
- Use sizeof() to get buffer size (instead of hardcoding macro name)
-
-Various pages
- Michael Kerrisk
- Use \(aq instead of ' inside monospace fonts
- Use \(aq to get an unslanted single quote inside monospace code
- blocks. Using a simple ' results in a slanted quote inside PDFs.
-
-Various pages
- Michael Kerrisk, Alejandro Colomar
- Use C99 style to declare loop counter variables
- Rather than:
-
- sometype x;
-
- for (x = ....; ...)
-
- use
-
- for (sometype x = ...; ...)
-
- This brings the declaration and use closer together (thus aiding
- readability) and also clearly indicates the scope of the loop
- counter variable.
-
-Various pages
- Alejandro Colomar
- Switch printf() casts to use [u]intmax_t + %ju / %jd
- Let's move to the 21st century. Instead of casting system data
- types to long/long long/etc. in printf() calls, instead cast to
- intmax_t or uintmax_t, the largest available signed/unsigned
- integer types.
-
-Various pages
- Alejandro Colomar
- Omit 'int' keyword for 'short', 'long' and 'long long' types
-
-Various pages
- Alejandro Colomar
- Remove unneeded casts
-
-Various pages
- Alejandro Colomar
- In printf(): s/0x%/%#/ except when followed by X instead of x
- Use printf()'s '#' flag character to prepend the string "0x".
-
- However, when the number is printed in uppercase, and the prefix
- is in lowercase, the string "0x" needs to be manually written.
-
-Various pages
- Michael Kerrisk
- Use C99-style declarations for readability
- Rather than writing things such as:
-
- struct sometype *x;
- ...
- x = malloc(sizeof(*x));
-
- let's use C99 style so that the type info is in the same line as
- the allocation:
-
- struct sometype *x = malloc(sizeof(*x));
-
-Various pages
- Alejandro Colomar
- Cast to 'unsigned long' rather than 'long' when printing with "%lx"
-
-stdarg.3
- Alejandro Colomar
- Declare variables with different types in different lines
- In particular, don's mix a variable and a pointer declaration
- on the same line: TYPE x, *p;
-
Changes to individual pages
---------------------------
-memusage.1
- Michael Kerrisk
- EXAMPLES: remove doubled calculations
- The same calculations are repeated in malloc() and printf() calls.

- Michael Kerrisk
- epoll instances can be nested to a maximum depth of 5

- EP_MAX_NESTS (4).
- Michael Kerrisk
- Move some version info from CONFORMING TO to VERSIONS
-
-eventfd.2
- Alejandro Colomar
- Use 'PRIxN' macros when printing C99 fixed-width integer types

- Highlight to the reader that if another filter returns a
- higher-precedence action value, then the ptracer will not
- be notified.
- Michael Kerrisk [Rich Felker]
- Warn against the use of SECCOMP_RET_KILL_THREAD
- Killing a thread with SECCOMP_RET_KILL_THREAD is very likely
- to leave the rest of the process in a broken state.
- Michael Kerrisk [Rich Felker]
- EXAMPLES: use SECCOMP_RET_KILL_PROCESS rather than SECCOMP_RET_KILL
- Alejandro Colomar

- Various ports that had their own indigenous system calls have
- been discontinued. Remove those system calls (none of which had
- manual pages!) to a separate part of the page, to avoid
- cluttering the main list of system calls.
- Michael Kerrisk
- Add close_range (Linux 5.9)
-
-timerfd_create.2
- Alejandro Colomar
- Use 'PRIxN' macros when printing C99 fixed-width integer types

- executable) that is relevant for the library search. Verified
- by experiment.
-
-errno.3
- Michael Kerrisk [Alejandro Colomar]
- Note that the pthreads APIs do not set errno

+ Alejandro Colomar
+ Create summary page for 'queue' APIs
+ The former queue(3) page was rather unwieldy, as it attempted to
+ describe too many APIs. After splitting that content out into a
+ number of smaller pages ( circleq.3, list.3, slist.3, stailq.3,
+ and tailq.3) move the much-reduced queue(3) page, which is now
+ essentially a summary of those APIs, from Section 3 to Section 7.

+Global changes
+--------------
+
+Various pages
+ Alejandro Colomar
+ Use ``sizeof`` consistently through all the examples in the
+ following way:
+
+ - Use the name of the variable instead of its type as argument for
+ ``sizeof``.
+
+Various pages
+ Alejandro Colomar
+ Use sizeof() to get buffer size (instead of hardcoding macro name)
+
+Various pages
+ Michael Kerrisk
+ Use \(aq instead of ' inside monospace fonts
+ Use \(aq to get an unslanted single quote inside monospace code
+ blocks. Using a simple ' results in a slanted quote inside PDFs.
+
+Various pages
+ Michael Kerrisk, Alejandro Colomar
+ Use C99 style to declare loop counter variables
+ Rather than:
+
+ sometype x;
+
+ for (x = ....; ...)
+
+ use
+
+ for (sometype x = ...; ...)
+
+ This brings the declaration and use closer together (thus aiding
+ readability) and also clearly indicates the scope of the loop
+ counter variable.
+
+Various pages
+ Alejandro Colomar
+ Switch printf() casts to use [u]intmax_t + %ju / %jd
+ Let's move to the 21st century. Instead of casting system data
+ types to long/long long/etc. in printf() calls, instead cast to
+ intmax_t or uintmax_t, the largest available signed/unsigned
+ integer types.
+
+Various pages
+ Alejandro Colomar
+ Omit 'int' keyword for 'short', 'long' and 'long long' types
+
+Various pages
+ Alejandro Colomar
+ Remove unneeded casts
+
+Various pages
+ Alejandro Colomar
+ In printf(): s/0x%/%#/ except when followed by X instead of x
+ Use printf()'s '#' flag character to prepend the string "0x".
+
+ However, when the number is printed in uppercase, and the prefix
+ is in lowercase, the string "0x" needs to be manually written.
+
+Various pages
+ Michael Kerrisk
+ Use C99-style declarations for readability
+ Rather than writing things such as:
+
+ struct sometype *x;
+ ...
+ x = malloc(sizeof(*x));
+
+ let's use C99 style so that the type info is in the same line as
+ the allocation:
+
+ struct sometype *x = malloc(sizeof(*x));
+
+Various pages
+ Alejandro Colomar
+ Cast to 'unsigned long' rather than 'long' when printing with "%lx"
+
+stdarg.3
+ Alejandro Colomar
+ Declare variables with different types in different lines
+ In particular, don's mix a variable and a pointer declaration
+ on the same line: TYPE x, *p;
+
+
+Changes to individual pages
+---------------------------
+
+memusage.1
+ Michael Kerrisk
+ EXAMPLES: remove doubled calculations
+ The same calculations are repeated in malloc() and printf() calls.
+ For better readability, do the calculations once.
+ Michael Kerrisk
+ Use %zu rather than %zd when printing 'size_t' values
+
+clock_getres.2
+ Alejandro Colomar
+ EXAMPLES: use 'const' when appropriate
+ Alejandro Colomar [Jakub Wilk]
+ Cast 'time_t' to 'int' for printf() and fix the length modifiers
+ Michael Kerrisk [Tony May]
+ Fix type and variable name in dynamic clock code example
+
+clone.2
+ Michael Kerrisk
+ CAP_CHECKPOINT_RESTORE can now be used to employ 'set_tid'
+
+epoll_ctl.2
+ Michael Kerrisk
+ epoll instances can be nested to a maximum depth of 5
+ This limit appears to be an off-by-one count against
+ EP_MAX_NESTS (4).
+ Michael Kerrisk
+ Move some version info from CONFORMING TO to VERSIONS
+
+eventfd.2
+ Alejandro Colomar
+ Use 'PRIxN' macros when printing C99 fixed-width integer types

+
+open_by_handle_at.2
+ Alejandro Colomar
+ Use "%u" rather than "%d" when printing 'unsigned int' values
+
+perf_event_open.2
+ Alexey Budankov

+ higher-precedence action value, then the ptracer will not
+ be notified.
+ Michael Kerrisk [Rich Felker]
+ Warn against the use of SECCOMP_RET_KILL_THREAD
+ Killing a thread with SECCOMP_RET_KILL_THREAD is very likely
+ to leave the rest of the process in a broken state.
+ Michael Kerrisk [Rich Felker]
+ EXAMPLES: use SECCOMP_RET_KILL_PROCESS rather than SECCOMP_RET_KILL
+ Alejandro Colomar
+ Use ARRAY_SIZE() macro instead of raw sizeof division

+ Various ports that had their own indigenous system calls have
+ been discontinued. Remove those system calls (none of which had
+ manual pages!) to a separate part of the page, to avoid
+ cluttering the main list of system calls.
+ Michael Kerrisk
+ Add close_range (Linux 5.9)
+
+timerfd_create.2
+ Alejandro Colomar
+ Use 'PRIxN' macros when printing C99 fixed-width integer types

+ executable) that is relevant for the library search. Verified
+ by experiment.
+
+errno.3
+ Michael Kerrisk [Alejandro Colomar]
+ Note that the pthreads APIs do not set errno
+
+fopencookie.3
+ Alejandro Colomar

+ Group all of these capabilities together in the list under
+ CAP_SYS_ADMIN, to make it clear that there is a pattern to these
