Heinrich Schuchardt 864eccb901 fanotify.7: fanotify_read should use aligned buffer 
Michael Kerrisk pointed me to alignment issues which may
arise when reading misaligned integers.

On some systems integer values can only be read if they are
correctly aligned. Other system have a lower performance when
reading from or writing to misaligned memory positions.

Therefore, the buffer used to call read(2) for a fanotify
file descriptor should have the same alignment as
struct fanotify_event_metadata.

Due to the casting to char* inside the macros
FAN_EVENT_OK and FAN_EVENT_NEXT we can use any
data structure for the buffer.

With the patch an array of struct fanotify_event_metadata is
used as buffer which seems a natural choice to ensure proper
alignment.

It should be remembered that the offset between events is given
by field event_len and iterating over the array may not be
allowable in future. Instead the macros should be used.

README 

This package contains Linux man pages for sections
2, 3, 4, 5, and 7. Some more information is given in the
`Announce' file.

Install by copying to your favourite location.
"make install" will just copy them to /usr/share/man/man[1-8].
"make" will move the pages from this package that are older than
the already installed ones to a subdirectory `not_installed',
then remove old versions (compressed or not),
compress the pages, and copy them to /usr/share/man/man[1-8].


Note that you may have to remove preformatted pages.

Note that sometimes these pages are duplicates of pages
also distributed in other packages. This has been reported
about dlclose.3, dlerror.3, dlopen.3, dlsym.3 (found in ld.so),
about resolver.3, resolv.conf.5 (found in bind-utils),
and about passwd.5, and mailaddr.7. Be careful not to
overwrite more up-to-date versions.
Reports on further duplicates are welcome.
Formerly present and now removed duplicates:
 exports.5 (found in nfs-server-2.2*),
 fstab.5, nfs.5 (found in util-linux-2.12*),
 lilo.8, lilo.conf.5 (found in lilo-21.6*).

Copyrights: These man pages come under various copyrights.
All pages are freely distributable when the nroff source is included.
