hello,
here is a small patch that adds the "change attribute" for ext3
file-systems;
the change attribute is a simple counter that is reset to zero on
inode creation and that is incremented every time the inode data is
modified (similarly to the "ctime" time-stamp).
Its purpose is to make possible to watch a file for changes, as
in the following pseudo-code:
stat(filename, oldsb);
... /* do something */
stat(filename, newsb);
if (oldsb->st_ctime != newsb->st_ctime ||
oldsb->st_change_attribute != newsb->st_changeattribute) {
/* file changed */
} else {
/* file didn't change */
}
The patch also adds a new ``st_change_attribute'' field in the stat
structure, and modifies the stat(2) syscall accordingly. Currently the
change is only visible on i386 and x86_64 archs.
In order to test the patch, there's a trivial utility that displays the
value of the change attribute:

Comments?
cheers,
