Dear kernel hackers,
after programming at least 10 scripts polling a what we call
"hot-folder" for new files I had the idea to integrate call backs into
the file system layer of the linux kernel.
I would like to tell the kernel to callback my program whenever a file
or directory is being inserted, updated or deleted.
A simple approach could look like this (from the users POV):
mount -o callback=/tmp/myprogram callback_options=some_options
callback_folder=hotfolder callback_folder=hotfolder2 /dev/some /home
depending on what has happend in "hotfolder" or "hotfolder2" the
"myprogram" would be started and receive the two arguments:
DELETE filename of the file deleted
UPDATE filename
INSERT filename
It would be neat if one could change the mount options while the
filesystem is mounted.
If you could implement such a feature we had another great argument why
the linux kernel has something to offer which others haven't. With such
a feature one could program solutions for the real world which are
always annoying to program (cue: "hotfolder"!).
What do you people think about the idea? Please reply to me personally,
too, I'm not a subscriber.
Thanks for taking a look at the idea.
;Martin
