Various edits and improvements to Cyrill's patch
|

|

|
||||
Changes to individual pages
|
||||
---------------------------
|
||||
|
||||
epoll_create.2
|
||||
Michael Kerrisk
|
||||
Rework discussion of 'size' argument
|
||||
Michael Kerrisk
|
||||
Add .SS for description of epoll_create1()
|
||||
|
||||
epoll_wait.2
|
||||
Michael Kerrisk [Armin Rigo]
|
||||
Another thread can add to epoll instance while epoll_wait is blocked
|
||||
See https://bugzilla.kernel.org/show_bug.cgi?id=43072
|
||||
Michael Kerrisk
|
||||
Clarify that epoll_pwait() blocks calling *thread*
|
||||
A few wording improvements
|
||||
|
||||
fchmodat.2
|
||||
Michael Kerrisk [Mike Frysinger]
|
||||
Note difference between glibc wrapper and underlying system call
|
||||
The wrapper function has a 'flags' argument (which currently
|
||||
serves no purpose), while the underlying system call does not.
|
||||
|
||||
fcntl.2
|
||||
Abhijith Das
|
||||
Explain behaviour of F_GETLEASE during lease break
|
||||
Michael Kerrisk [Eric Blake]
|
||||
Change type of arg from "long" to "int"
|
||||
Various fcntl(2) commands require an integral 'arg'.
|
||||
The man page said it must be "long" in all such cases.
|
||||
However, for the cases covered by POSIX, there is an
|
||||
explicit requirement that these arguments be "int".
|
||||
Update the man page to reflect. Probably, all of the
|
||||
other "long" cases (not specified in POSIX) should
|
||||
be "int", and this patch makes them so. Based on a
|
||||
note fromEric Blake, relating to F_DUPFD_CLOEXEC.
|
||||
|
||||
gettimeofday.2
|
||||
Michael Kerrisk
|
||||
Reorganize content
|
||||
The main change is to move the historical information about
|
||||
the 'tz_dsttime' to NOTES.
|
||||
Michael Kerrisk [Felix]
|
||||
Note that compiler issues warnings if 'tv' is NULL
|
||||
|
||||
mmap.2
|
||||
Michael Kerrisk [Kevin O'Gorman]
|
||||
Clarify that this system call should not be invoked directly
|
||||
See https://bugzilla.kernel.org/show_bug.cgi?id=42892
|
||||
Michael Kerrisk
|
||||
Clarify NOTES discussion of mmap() versus mmap2()
|
||||
|
||||
poll.2
|
||||
Michael Kerrisk [Michael Welsh Duggan]
|
||||
Document negative value in 'fd' field
|
||||
Michael Kerrisk
|
||||
Document semantics of passing zero in 'events' field
|
||||
|
||||
ptrace.2
|
||||
Denys Vlasenko
|
||||
Various fixes
|
||||
For some reason, the PTRACE_TRACEME paragraph talks about some
|
||||
general aspects of ptraced process behavior. It repeats the
|
||||
"tracee stops on every signal" information even though that was
|
||||
already explained just a few paragraphs before. Then it describes
|
||||
legacy SIGTRAP on execve().
|
||||
|
||||
This patch deletes the first part, and moves the second part up,
|
||||
into the general ptrace description. It also adds
|
||||
"If PTRACE_O_TRACEEXEC option is not in effect" to the description
|
||||
of the legacy SIGTRAP on execve().
|
||||
|
||||
The patch also amends the part which says "For requests other
|
||||
than PTRACE_KILL, the tracee must be stopped." - PTRACE_ATTACH
|
||||
also doesn't require that.
|
||||
|
||||
sigaction.2
|
||||
Michael Kerrisk [Andreas Jaeger, ]
|
||||
Clarify that the use of SI_SIGIO is for Linux 2.2 only
|
||||

nologin.5
|
||||
Michael Kerrisk [Tetsuo Handa]
|
||||

|
||||
|
||||
nsswitch.conf.5
|
||||
Mark R Bannister
|
||||
Significant rewrites and improvements
|
||||
This patch applies to nsswitch.conf.5 in man-pages-3.36.
|
||||
|
||||
My changes almost completely rewrite large sections of the
|
||||
man page. They are needed to add clarity, correct grammar,
|
||||
reduce confusion, and bring up-to-date with the latest glibc.
|
||||
I have checked the man page against the nss source code in
|
||||
glibc 2.14.90.
|
||||
|
||||
Historical notes are demoted to the footer.
|
||||
|
||||
The rewrite makes the man page much clearer to
|
||||
understand, more authoratitive, and easier to read.
