Subject: man-pages-3.25 is released
Gidday,
I've released man-pages-3.25.tar.gz - man pages for Linux
This release is now available for download at:
http://www.kernel.org/pub/linux/docs/man-pages
or ftp://ftp.kernel.org/pub/linux/docs/man-pages
man-pages nowadays also has a public git repository at
git://git.kernel.org/pub/scm/docs/man-pages/man-pages.git
The online changelog is available at
http://www.kernel.org/doc/man-pages/changelog.html (blogged at
http://linux-man-pages.blogspot.com/2010/06/man-pages-325-is-released.html
) and the current version of the pages is browsable at

An abridged list of changes that may be of interest to readers of this

Cheers,
Michael
==================== Changes in man-pages-3.25 ====================
New and rewritten pages
-----------------------
migrate_pages.2
Andi Kleen
New page documenting migrate_pages(2).
Andi's text based on the move_pages.2 page;
additional edits by mtk.
migrate_pages(2) was new in Linux 2.6.16.
quotactl.2
Jan Kara
Major updates
Update the page to consolidate information from the
outdated man-pages quotactl.2 page and the quotactl.2
page in the "quota-tools" pachage. The page in "quota-tools"
has now been dropped by Jan Kara, so that there is just one
canonical quotactl.2 page (in pan-pages).
Michael Kerrisk
Various other pieces added to the page by mtk.
Newly documented interfaces in existing pages
---------------------------------------------

Note that glibc 2.11 papers over the kernel F_GETOWN bug
Since version 2.11, glibc works around the kernel limitation for
process groups IDs < 4096 by implementing F_GETOWN via F_GETOWN_EX.
