Re: inotify and sysfs

  Hi Andruk,
this mailing list is mainly for discussion about incron and inotify-cxx.
It may be used for discussion about inotify too but because inotify is
an integral part of the kernel its better to communicate with the
appropriate developers/maintainers directly. We can help you some way
but we can't resolve any problems related to the inotify implementation
the rather that the problems are often in other parts of the kernel than
inotify. sysfs is a "non-standard" filesystem. If the sysfs file you
need to monitor doesn't generate inotify events you can't use inotify to
monitor it. Please contact the sysfs maintainers to consult why it's
implemented this way and whether there is possibility to change it in
the future kernel releases.
