Michael Kerrisk b44cf4bcd4 dlopen.3: Correct the pathname used in EXAMPLE 
Quoting Florian:

    This does not work because libm.so can be a linker script:

           handle = dlopen("libm.so", RTLD_LAZY);

    The proper way to do this is to include <gnu/lib-names.h>
    and use LIBM_SO.

Michael Kerrisk 614e5d137a daemon.3: Minor wording fix 
As noted by Florian Weimer:

    The manual daemon(3) manual page talks about the "calling
    process's current working directory".  I think this is
    misleading because the function exits the calling process
    before changing the current directory.

Olivier TARTROU 2d7c8f1f78 termios.3: Add missing details on behaviour of PARMRK 
For a serial terminal, with a specific configuration, input bytes
with value 0377 are passed to the program as two bytes, 0377 0377.

This (correct) behaviour is described in the documentation of the
GNU C Library
(https://www.gnu.org/software/libc/manual/html_node/Input-Modes.html#Input-Modes)
but not in the termios.3 man page.

Problematic configuration: INPCK set, IGNPAR not set, PARMRK set,
ISTRIP not set.

This man page problem affects several users. Examples:
* http://sourceforge.net/p/ftdi-usb-sio/mailman/message/4079724/
* http://mailman.uclinux.org/pipermail/uclinux-dev/2006-November/040984.html

Carlos O'Donell a74bc4c9e4 posix_fallocate.3: Mention glibc emulation caveats 
When the glibc implementation of posix_fallocate detects
that the underlying filesystem does not support fallocate()
it uses an emulation function to attempt to allocate the
space requested. The most common case is calling
posix_fallocatei() for a file that is on NFS where the
NFS server is not new enough to support the recent fallocate
extensions. This emulation has various serious caveats that
must be understood in order to use posix_fallocate robustly
on all filesystems. The change documents the caveats in the
glibc implementation.

Lastly, we expand the meaning of EINVAL to match POSIX
2013 (Issue 7). If the underlying filesystem doesn't support
posix_fallocate()i, the implementation can return EINVAL, but
glibc does not do this, it emulates the operation instead.

Carlos O'Donell 9d116bd272 mallopt.3: Document M_ARENA_TEST and M_ARENA_MAX 
In 2013 I brought up the discussion if M_ARENA_MAX and M_ARENA_TEST
were public parameters:
https://sourceware.org/ml/libc-alpha/2013-03/msg00376.html
Consensus among Siddhesh and myself was that they should be
public, and in fact they were already in the public header.
Therefore there may already be applications uses these constants
and expecting them to work. At best we could limit mallopt()'s
acceptance of the options, but that seems like a bad solution
that could lead to unexpected behavior for user applications.
A quick google search shows that there are packages relying on
these constants to tune the glibc malloc implementation.

Since glibc 2.10 the M_ARENA_TEST and M_ARENA_MAX features
have been part of the public interface with
--enable-experimental-malloc.

Since glibc 2.15 the experimental allocator has been on by default
and M_ARENA_TEST and M_ARENA_MAX have been more broadly used.

There are environment variables, without trailing underscore, that
can also be used to adjust these values at runtime i.e.
MALLOC_ARENA_MAX, and MALLOC_ARENA_TEST.

This change describes these two options in the mallopt(3) man page
along with their environment variables.

Tested with glibc master on x86_64 to verify it works as expected.
