2023-10-31man*/: srcfix (Use .P instead of .PP or .LP)Alejandro Colomar1-14/+14
We're trying to "standardize" on a paragraphing macro from the three equivalent ones (P, PP, LP). We (somewhat arbitrarily) agreed on P.

2023-03-30man*/, man-pages.7: VERSIONS, STANDARDS, HISTORY: Reorganize sectionsAlejandro Colomar1-7/+6
- Add a new HISTORY section that covers the history of an API, both regarding implementations and regarding old standards. This was previously covered in VERSIONS, and in some cases in STANDARDS. - Repurpose VERSIONS to cover differing implementations in _current_ systems. - STANDARDS is reduced to only cover current versions of standards. That basically means only C11 (C99 has been superseeded by C11; C17 is just a bugfix of C11, so not really a new version), and POSIX.1-2008 (*-2001 was superseeded by *-2008; *-2017 was just a bugfix for *-2008). The section also mentions for example 'Linux', 'GNU' or 'BSD' when a non-standard API is Linux- or GNU-only or if it's (de-facto) standard in the BSDs. - In some cases content that should go into one of these sections was in NOTES. Move it from there to where it corresponds. - In the SYNOPSIS, I added [[deprecated]] in some functions that I found are deprecated by the relevant standards. - A few other related changes...

2022-11-01madvise.2: add documentation for MADV_COLLAPSEZach O'Keefe1-0/+10
Linux 6.1 introduced MADV_COLLAPSE in upstream commit 7d8faaf15545 ("mm/madvise: introduce MADV_COLLAPSE sync hugepage collapse") and upstream commit 34488399fa08 ("mm/madvise: add file and shmem support to MADV_COLLAPSE"). Update the man-pages for madvise(2) and process_madvise(2).

2022-10-31process_madvise.2: fix capability and ptrace requirementsZach O'Keefe1-4/+17
The initial commit of process_madvise(2) to Linux, commit ecb8ac8b1f14 ("mm/madvise: introduce process_madvise() syscall: an external memory hinting API"), relied on PTRACE_MODE_ATTACH_FSCREDS (see ptrace(2)), but was amended by commit 96cfe2c0fd23 ("mm/madvise: replace ptrace attach requirement for process_madvise") which replaced this with a combination of PTRACE_MODE_READ and CAP_SYS_NICE (PTRACE_MODE_READ to prevent leaking ASLR metadata and CAP_SYS_NICE for influencing process performance). The initial commit of process_madvise(2) to man-pages project, made after the second patch, included two errors: 1) CAP_SYS_ADMIN instead of CAP_SYS_NICE 2) PTRACE_MODE_READ_REALCREDS instead of PTRACE_MODE_READ_FSCREDS Correct this in the man-page for process_madvise(2).

2022-09-05src.mk, All pages: Move man* to man/Alejandro Colomar1-187/+0
The root of the repository is becoming a bit overpopulated and unorganized, due to the recent addition of more mandirs, and more informative and configuration files too. Let's create a specific mandir <man/> that contains the mandirs <man[1-8]*>. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>
2022-08-21All pages: Remove the 5th argument to .THAlejandro Colomar1-1/+1
Now that we have the LIBRARY section, and a 4th argument that already tells that it's a page from the Linux man-pages project, the 5th argument isn't telling any information that the default value wouldn't. So let's just remove it. Scripted change: $ find man* -type f \ | xargs sed -Ei '/^.TH /s/(.TH +[^ ]+ +[^ ]+ +[^ ]+ +"[^"]+") .*/\1/' Acked-by: "G.

2022-07-29Many pages: Use STANDARDS instead of CONFORMING TOAlejandro Colomar1-1/+1
STANDARDS seems to be much more extended than CONFORMING TO. For consistency across the whole manual pages corpus, let's try to unify, by following the most commonly used section name.
