Global changes
--------------
Typographical or grammatical errors have been corrected in several
places.
Various pages
mtk
Use 'glibc' consistently to refer to GNU C library.
Various pages
mtk
Order errors under ERRORS alphabetically.
Various pages
Nicolas Fran�ois
Spelling and formatting fixes, as per Debian bug 439560.
intro.2

New pages
---------
timeradd.3
mtk
Description of timeradd(), timersub(), timerclear(),
timerisset(), timercmp() macros for operating on
struct timeval.
Removed pages
-------------
fdatasync.2
mtk
Somehow, over time, material on fdatasync(2) crept into
fsync.2, and fdatasync also got added to the NAME section
of fsync.2. All of the material in fdatasync.2 that was
not already in fsync.2 has now been moved there, and
the former page has been removed.
In place of the content there, is now a link to fsync.2.
New links
---------
clock_getres.2
clock_gettime.2
clock_settime.2
mtk
Link to man3/clock_getres.3.

timerclear.3
timercmp.3
timerisset.3
timersub.3
mtk
Links to new timeradd.3.
Changes to individual pages
---------------------------
Makefile
Mike Frysinger
Make the install target of man-pages respect the standard
"DESTDIR" variable as well as check the exit status of the
install command so errors aren't ignored.
get_mempolicy.2
Lee Schermerhorn
changed the "policy" parameter to "mode" through out the
descriptions in an attempt to promote the concept that the memory
policy is a tuple consisting of a mode and optional set of nodes.
added requirement to link '-lnuma' to synopsis
rewrite portions of description for clarification.
added all errors currently returned by sys call.
removed cautionary note that use of MPOL_F_NODE|MPOL_F_ADDR
is not supported. This is no longer true.
added mmap(2) to See Also list.
getitimer.2
mtk
Since kernel 2.6.22, Linux setitimer() now conforms to POSIX.1,
giving an EINVAL error for a non-canonical tv_usec value.
gettimeofday.2
mtk
Replace discussion of timer* macros with a pointer
to new page timeradd.3.
ioctl_list.2
Nicolas George
Fixed argument type for BLKGETSIZE.
mbind.2
Lee Schermerhorn
changed the "policy" parameter to "mode" throughout the
descriptions in an attempt to promote the concept that the memory
policy is a tuple consisting of a mode and optional set of nodes.
rewrite portions of description for clarification.
clarify interaction of policy with mmap()'d files and shared
memory regions, including SHM_HUGE regions.
defined how "empty set of nodes" specified and what this
means for MPOL_PREFERRED.
mention what happens if local/target node contains no
free memory.
clarify semantics of multiple nodes to BIND policy.
Note: subject to change. We'll fix the man pages when/if
this happens.
added all errors currently returned by sys call.
added mmap(2), shmget(2), shmat(2) to See Also list.
mmap.2
mprotect.2
Fran�ois Diakhate
Add text noting that PROT_WRITE may (and on x86 does)

Maxime Vaudequin
Fix path error (s%proc/sys%proc/sys/kernel%) in mentions of
/proc/sys/ostype, /proc/sys/osrelease and proc/sys/version.
Maxime Vaudequin
I noticed things to correct and to clarify in subsection
"/proc/filesystems" of proc.5:
- clarify filesystems listing: not only FS compiled
into the kernel, also FS kernel modules currently loaded
- add a reference to fs(5)
- add an explanation for FS marked with "nodev"
- s/mount(1)/mount(8)/, also corrected in section "SEE ALSO"
- clarify usage by mount: the current wording may lead to
think /proc/filesystems is always used by mount when no FS
is specified. So, usage of "may" which IMHO is more
appropriate + additional explanations
In mount(8) we can see:
If no -t option is given, or if the auto type is
specified, mount will try to guess the desired type.
If mount was compiled with the blkid library, the
guessing is done by this library. Otherwise, mount
guesses itself by probing the superblock; if that
does not turn up anything that looks familiar,
mount will try to read the file /etc/filesystems,
or, if that does not exist, /proc/filesystems.
All of the filesystem types listed there will be
tried, except for those that are labeled "nodev"
(e.g., devpts, proc and nfs). If /etc/filesystems
ends in a line with a single * only, mount will
read /proc/filesystems afterwards.
Samuel Thibault
Since linux 2.6.11, /proc/stat has an eighth value for cpu
lines: stolen time, which is the time spent in other operating
systems when running in a virtualized environment.
arp.7
Updated BUGS text referring to jiffies; refer to time.7 instead.
credentials.7
mtk
Add words to note that file system ID is Linux specific.
hier.7
Maxime Vaudequin
This is some corrections for hier.7:
- missing period for /media and /mnt
- /mnt description is not totally correct, it is true for some
distributions but in others /mnt is used as a temporary FS
mount point, as it is specified by FHS:
http://www.pathname.com/fhs/pub/fhs-2.3.html#
MNTMOUNTPOINTFORATEMPORARILYMOUNT
- s/X-Windows/X-Window/ (3 occurrences)
- section "SEE ALSO": s/mount(1)/mount(8)/
man-pages.7
man.7
mdoc.7
mdoc.samples.7
mtk / Nicolas Fran�ois
Nowadays tmac.XXX are called XXX.tmac.
pthreads.7
mtk
Update text about modern threading implementations
(NPTL vs LinuxThreads).
socket.7
mtk, after a note by Andi Kleen
Clarify that SO_SNDTIMEO and SO_RCVTIMEO only have effect for
socket I/O calls; not for multiplexing system calls like
select() and poll().
time.7
mtk
Add SEE ALSO reference to new timeradd.3.
