Updated: man-pages-linux 6.15 - Linux manual pages

[Cygwin Linux Man Pages Maintainer]

Documents the Linux kernel system calls and C library interfaces used
by programs, plus system and administrative utilities, devices, file
system, file, and data formats, and related information.

For more information, see the project home page:

	https://kernel.org/doc/man-pages/

As Cygwin has its own man pages with some conflicts, these man pages are
installed under /usr/share/man/man-pages-linux/, so by default searching
or viewing these pages requires the option:

	$ apropos -m|--systems man-pages-linux ...
	$ man -m|--systems man-pages-linux ...

Cygwin man pages are under the default system "man", so for convenience
both systems may be specified separated by comma e.g.

	$ man -m man,man-pages-linux ...

The path or option may also be added explicitly to a user's MANPATH or
alias e.g.

	$ export MANPATH=$MANPATH:/usr/share/man/man-pages-linux

	$ alias apropos='apropos -m man,man-pages-linux'
	$ alias man='man -m man,man-pages-linux'

Add -a to show both Cygwin and Linux (and POSIX if companion package
man-pages-posix is also installed) manual pages.

For convenience and backward compatibility /usr/share/man/linux is
provided as a symlink. 

If you prefer to see Linux man pages over Cygwin man pages, then use
-m|--systems linux in the examples above, or add -m linux to a command.

Release 6 and later added some section 2 and 3 pages suffixed by const,
head, or type installed in the base section directories.

The following package has been upgraded in the Cygwin distribution:

- man-pages-linux	6.15

Global changes

-  CREDITS renamed to AUTHORS.

-  man/
   -  realloc(3): Clarify (non)conformance of realloc(p,0) in glibc.
   -  Don't use bold/italics for forward declarations of function
      parameters.  This differentiates them from actual parameters.
   -  fcntl(2) and futex(2) have been split into smaller pages that are
      easier to read, and also easier to maintain.
