==================== Changes in man-pages-3.70 ====================
Released: 2014-07-08, Munich
New and rewritten pages
Michael Kerrisk [Marko Myllynen]
New page for the glibc sprof(1) command
Newly documented interfaces in existing pages
Changes to individual pages
Michael Kerrisk [Rich Felker]
Fix erroneous discussion regarding closing 'newfd' before calling dup2()
And propose a workaround if the caller cares about catching
close() time errors.
Rework and enhance discussion of dup2()
In particular, note that dup2() performs the steps of closing
and reusing 'newfd' atomically.
BUGS: EPOLLWAKEUP is silently ignored without CAP_BLOCK_SUSPEND
If the caller does not have CAP_BLOCK_SUSPEND, then EPOLLWAKEUP
is silently ignored.
Michael Kerrisk [Tomi Salminen]
The return value for F_SETPIPE_SZ is the pipe capacity
ERRORS: Document ENOTDIR error for F_NOTIFY
Suggest the use of real-time signals with F_NOTIFY
Clarify that the target of a watch is an i-node
The target of a watch is an i-node, not a pathname. Clarify
the text to prevent the reader possibly misunderstanding
that establishing watches by two different links to the same
file might create different watch descriptors.
Michael Kerrisk [ÐÐÑÐÐÐ]
O_CLOEXEC is also one the flags not ignored when O_PATH is specified
Explain SHMLBA in much more detail
Rework introductory paragraph
Michael Kerrisk [Robert P. J. Day]
Rework text describing loglevels
The kernel header file mentioned in the discussion of the KERN_*
constants has morphed and is no longer exported inside glibc.
And the definitions of the constants themselves changed subtly
with kernel commit 04d2c8c83d0e3ac5f78aeede51babb3236200112.
So, rewrite the description of the constants to be a bit more
Rewrite parts of the page, and import /proc/sys/kernel/printk
* Move /proc/sys/kernel/printk from proc(5) to this page,
and correct various details in the discussion of that file.
* Rewrite and correct various other details on the page.
* Clean out some crufty text.
* Miscellaneous minor fixes.
Update SYSLOG_ACTION_CONSOLE_OFF + SYSLOG_ACTION_CONSOLE_ON description
Details changed in Linux 2.6.32
Clarify which events are generated for watched directories
Really, with respect to watched directories, events fall into
three classes (not two, as was shown):
* Events that can be generated only for the watched directory.
* Events that can be generated only for objects that are inside
the watched directory.
* Events that can be generated both for the watched directory
and for objects inside the directory.
So, mark these three classes more clearly in the list of inotify
Heinrich Schuchardt [Michael Kerrisk]
BUGS: Note possible bug triggered by watch descriptor reuse
Watch descriptor IDs are returned by inotify_add_watch().
When calling inotify_rm_watch() an IN_IGNORE is placed on the
inotify queue pointing to the ID of the removed watch.
inotify_add_watch() should not return a watch descriptor ID for
which events are still on the queue but should return an
Unfortunately, the existing Kernel code does not provide such a
Actually, in rare cases watch descriptor IDs are returned by
inotify_add_watch() for which events are still on the inotify

Add reference that the pipe capacity can be changed
In fcntl(2) F_SETPIPE_SZ, F_GETPIPE_SZ and
/proc/sys/fs/pipe-max-size are defined, however
pipe(7) still defines the pipe capacity as being
a static entity. Adding a reference to fcntl(2).
Clarify that LD_PROFILE can specify just a single shared object
Clarify that LD_PROFILE output is appended to target file
The LD_PROFILE output is appended to any existing
contents of the target file.
