Description Shijin Kong 2007-07-19 09:03:29 UTC

Most recent kernel where this bug did not occur: none
Distribution: Fedora Core 6
Hardware Environment: i386 32bit PC
Software Environment: Default installation of FC6
Problem Description:

I could not detect some notification from inotify mechanism when adding watches to /proc file system, including IN_CREATE/IN_DELETE. I think the reason is that inotify is not built in /proc (loss of functions), although it's pretty useful. 

We start to develop some software based on that feature (if it could exist).

I found an old message to resolve this problem:
http://www.ussg.iu.edu/hypermail/linux/kernel/0602.2/1815.html

That patch was introduced soon after inotify was built into kernel 2.6.13. However the patch is not applied until now. I just suggest that inotify on /proc should be built in future kernel versions.

Thank.

Patch broken as-is. Connector interface is already available.
