- documentation-move-dnotifytxt-to-filesystems.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     Documentation: move dnotify.txt to filesystems/
has been removed from the -mm tree.  Its filename was
     documentation-move-dnotifytxt-to-filesystems.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

------------------------------------------------------
Subject: Documentation: move dnotify.txt to filesystems/
From: "J. Bruce Fields" <bfields@citi.umich.edu>

I'm inclined to think dnotify belongs in filesystems/.

-		Linux Directory Notification
-		============================
-
-	   Stephen Rothwell <sfr@canb.auug.org.au>
-
-The intention of directory notification is to allow user applications
-to be notified when a directory, or any of the files in it, are changed.
-The basic mechanism involves the application registering for notification
-on a directory using a fcntl(2) call and the notifications themselves
-being delivered using signals.
-
-The application decides which "events" it wants to be notified about.
-The currently defined events are:
-
-	DN_ACCESS	A file in the directory was accessed (read)
-	DN_MODIFY	A file in the directory was modified (write,truncate)
-	DN_CREATE	A file was created in the directory
-	DN_DELETE	A file was unlinked from directory
-	DN_RENAME	A file in the directory was renamed
-	DN_ATTRIB	A file in the directory had its attributes
-			changed (chmod,chown)
-
-Usually, the application must reregister after each notification, but
-if DN_MULTISHOT is or'ed with the event mask, then the registration will
-remain until explicitly removed (by registering for no events).
-
-By default, SIGIO will be delivered to the process and no other useful
-information.  However, if the F_SETSIG fcntl(2) call is used to let the
-kernel know which signal to deliver, a siginfo structure will be passed to
-the signal handler and the si_fd member of that structure will contain the
-file descriptor associated with the directory in which the event occurred.
-
-Preferably the application will choose one of the real time signals
-(SIGRTMIN + <n>) so that the notifications may be queued.  This is
-especially important if DN_MULTISHOT is specified.  Note that SIGRTMIN
-is often blocked, so it is better to use (at least) SIGRTMIN + 1.
-
-Implementation expectations (features and bugs :-))
----------------------------
-
-The notification should work for any local access to files even if the
-actual file system is on a remote server.  This implies that remote
-access to files served by local user mode servers should be notified.
-Also, remote accesses to files served by a local kernel NFS server should
-be notified.
-
-In order to make the impact on the file system code as small as possible,
-the problem of hard links to files has been ignored.  So if a file (x)
-exists in two directories (a and b) then a change to the file using the
-name "a/x" should be notified to a program expecting notifications on
-directory "a", but will not be notified to one expecting notifications on
-directory "b".
-
-Also, files that are unlinked, will still cause notifications in the
-last directory that they were linked to.
-
-Configuration
--------------
-
-Dnotify is controlled via the CONFIG_DNOTIFY configuration option.  When
-disabled, fcntl(fd, F_NOTIFY, ...) will return -EINVAL.
-
-Example
--------
-
-	#define _GNU_SOURCE	/* needed to get the defines */
-	#include <fcntl.h>	/* in glibc 2.2 this has the needed
-					   values defined */
-	#include <signal.h>
-	#include <stdio.h>
-	#include <unistd.h>
-	
-	static volatile int event_fd;
-	
-	static void handler(int sig, siginfo_t *si, void *data)
-	{
-		event_fd = si->si_fd;

-	
-	int main(void)

-		act.sa_sigaction = handler;

-		act.sa_flags = SA_SIGINFO;
-		sigaction(SIGRTMIN + 1, &act, NULL);
-		
-		fd = open(".", O_RDONLY);
-		fcntl(fd, F_SETSIG, SIGRTMIN + 1);
-		fcntl(fd, F_NOTIFY, DN_MODIFY|DN_CREATE|DN_MULTISHOT);
