more so than previosly updated kernel packages



Lo!

Updated inotify kernel packages are available with the freshest inotify
support to date.  The version is 747.inotify.0.

UP:
http://primates.ximian.com/~rml/kernel-rml/nld-9-i586/kernel-default-2.6.5-747.inotify.0.i586.rpm

SMP:
http://primates.ximian.com/~rml/kernel-rml/nld-9-i586/kernel-smp-2.6.5-747.inotify.0.i586.rpm

Source:

The bulk of the changes in this revision are bug fixes and optimization.
I still have a handful of feature changes outstanding, however.  With
luck they will happen this week.

NOTE: THIS KERNEL BREAKS ABI OH-SO-SLIGHTLY !!!

I moved the variables in the user-visible inotify_event structure to
fixed-sized types, to ensure portability on systems where kernel- and
user-space have a different ABI (this is mainly an issue on systems with
a 64-bit kernel but a 32-bit user-space).

Nothing changed (e.g. "int" types are now "s32" types) except that mask
is now unsigned ("u32").  Please update any user-space code to match
this.

An updated inotify.h is attached.

Best,

	Robert Love
