==================== Changes in man-pages-3.54 ====================

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.

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


Changes to individual pages
---------------------------

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.

setfsgid.2
Michael Kerrisk [Oleg Nesterov]
Clarify description of return value
More clearly describe the weirdness in the return value of this
system call, and note the problems it creates in BUGS
Michael Kerrisk
Refer to setfsuid(2) for an explanation of why setfsgid() is obsolete

setfsuid.2
Michael Kerrisk [Oleg Nesterov]
Clarify description of return value
More clearly describe the weirdness in the return value of this
system call, and note the problems it creates in BUGS
Michael Kerrisk [Chen Gang]
Clarify historical details and note that setfsuid() is obsolete

wait.2
Michael Kerrisk [Hannes Landeholm]
Add details on the fifth argument provided by raw waitid() system call
See https://bugzilla.kernel.org/show_bug.cgi?id=60744

proc.5
Peter Schiffer
Document /proc/[pid]/io file
Attempt to document fields in the /proc/[pid]/io file, based on
the Documentation/filesystems/proc.txt. The text will probably
need some grammar corrections.
Michael Kerrisk [Marko Myllynen]
/proc/sys/fs/inode-max went away in Linux 2.4
Also, the 'preshrink' field in /proc/sys/fs/inode-state became
a dummy value in Linux 2.4.

See https://bugzilla.kernel.org/show_bug.cgi?id=60836
Michael Kerrisk [A. Costa]
Note block size used by /proc/partitions
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=666972
Michael Kerrisk
Add rationale on drop_caches and note that it can hurt performance

ip.7
Simon Paillard
IP_MULTICAST_IF setsockopt recognizes struct mreq (compatibility)
Kernel added compatibility only recently in
3a084ddb4bf299a6e898a9a07c89f3917f0713f7
See: http://bugs.debian.org/607979

standards.7
Michael Kerrisk
Add mention of SUSv4-TC1 (POSIX.1-2013)
