Hi All, Recently i have implemented fairly simple IPC between two processes by mmap-ing the same file in both. To send an "event" from one process to the other i thought of using msync() and inotify. I found that there is no inotify event that can be triggered upon msync() on a mmap-ed file. Luckily i was able to patch the kernel and add a new watch to inotify that is triggered upon msync. https://gist.github.com/TheCodeArtist/5874669 This is derived from a previous work by Simo Sorce(wayyy back in 2009) http://osdir.com/ml/linux-kernel/2009-03/msg13455.html This is NOT part of the mainline kernel yet. Does this approach have any technical "gotchas"? _OR_ is there a far simpler approach i am missing? thanks & regards ChinmayVS -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
