New and rewritten pages
|
||||
-----------------------
|
||||
|
||||
|
||||
Newly documented interfaces in existing pages
|
||||
---------------------------------------------
|
||||
|
||||
ioctl_list.2
|
||||
Zsbán Ambrus
|
||||
Document FAT_IOCTL_GET_ATTRIBUTES
|
||||
The attached patch adds four ioctls from linux/msdos_fs.h to the
|
||||
ioctl_list(2) manpage.
|
||||
|
||||
New and changed links
|
||||
---------------------
|
||||
The ioctl FAT_IOCTL_GET_ATTRIBUTES reads FAT attributes of a
|
||||
file a mounted vfat file system. I tested this on Linux
|
||||
2.6.33, an example script can be found at
|
||||
http://www.perlmonks.com/?node_id=832623
|
||||
|
||||
|
||||
Global changes
|
||||
--------------
|
||||
|
||||
Various pages
|
||||
Michael Kerrisk
|
||||
Global fix: s/file system/filesystem/
|
||||
Notwithstanding 24d01c530c5a3f75217543d02bf6712395e5f90c,
|
||||
"filesystem" is the form used by the great majority of man pages
|
||||
outside the man-pages project and in a number of other sources,
|
||||
so let's go with that.
|
||||
|
||||
|
||||
Changes to individual pages
|
||||
---------------------------
|
||||
|
||||
access.2
|
||||
J. Bruce Fields
|
||||
Fix outdated NFS information
|
||||
Note that NFS versions since version 3 support an "access" call
|
||||
so that the client doesn't have to guess permissions or ID
|
||||
mapping on its own.
|
||||
|
||||
(See RFC 1813 sections 1.7 and 3.3.4.)
|
||||
|
||||
adjtimex.2
|
||||
Michael Kerrisk
|
||||
SEE ALSO: Add adjtimex(8)
|
||||
|
||||
clock_getres.2
|
||||
Michael Kerrisk [Rodrigo Campos]
|
||||
Note circumstances in which "SMP" note applies.
|
||||
Michael Kerrisk
|
||||
Add kernel version for CLOCK_*_CPUTIME_ID
|
||||
CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID
|
||||
appeared in 2.6.12.
|
||||
Michael Kerrisk
|
||||
Add VERSIONS section
|
||||
|
||||
futex.2
|
||||
Michael Kerrisk
|
||||
The 'timeout' can be rounded upwards by clock granularity and also overrun
|
||||
|
||||
kill.2
|
||||
Michael Kerrisk
|
||||
Small improvements to text on historical rules for permissions
|
||||
|
||||
nfsservctl.2
|
||||
Michael Kerrisk
|
||||
Note commands that were only in Linux 2.4.x and earlier
|
||||
|
||||
open.2
|
||||
Robert Harris
|
||||
Add mmap(2) to list of calls that fail when given an O_PATH descriptor
|
||||
Doug Goldstein
|
||||
Add EINVAL to errors list
|
||||
EINVAL can be returned by open(2) when the underlying filesystem
|
||||
doesn't support O_DIRECT. It is documented in the NOTES section
|
||||
but this patch adds it to the list of possible errors.
|
||||
|
||||
perf_event_open.2
|
||||
Vince Weaver
|
||||
PERF_SAMPLE_BRANCH_STACK updates
|
||||
This started out as just adding the new perf_event_open features
|
||||
from Linux 3.11 (which was the addition of transactional memory
|
||||
defines for PERF_SAMPLE_BRANCH_STACK samples) but turned into a
|
||||
general cleanup of the PERF_SAMPLE_BRANCH_STACK documentation.
|
||||
|
||||
The main clarification is that at least one of the non-privilege
|
||||
values must be set or else perf_event_open() will return an EINVAL
|
||||
error.
|
||||
Michael Kerrisk
|
||||
Reorder text describing fields of 'perf_event_header' structure
|
||||
Place the fields with the shorter descriptions first, to make the
|
||||
information easier to read.
|
||||
|
||||
poll.2
|
||||
Michael Kerrisk
|
||||

printf.3
|
||||
Christopher Hall
|

Correctly describe the meaning of a negative precision
|
||||
The printf(3) manpage says that a negative precision is taken to

||||
be zero, whereas printf(3p) says that a negative precision is

||||
taken as if the precision were omitted. glibc agrees with the
|
||||
latter (POSIX) specification.
|
||||
|
||||
Test code:
|
||||
|
||||
printf("%f\n",42.0); // "42.000000"
|
||||
printf("%.*f\n",0,42.0); // "42"
|
||||
printf("%.*f\n",-1,42.0); // "42.000000"
|
||||
|
||||
This patch corrects the explanation to match what actually happens.

the Documentation/filesystems/proc.txt. The text will probably
