I am not sure - but it is obviously required that inotify can pass over CIFS (and probably NFS) since change notification is hardest for the user to figure out when they are on a network. I am not sure how the filesystem can detect that a new watch is added to one of its inodes - it looks like you added an ioctl to a device but I am still reading through your latest patch. I was looking for something like an inode operation that cifs could hook so the fs could be told when a new watch was added or one was changed. In any case I need to construct functions somewhat similar to what is in fs/cifs/fcntl.c and need to finish/modify CIFSSMBNotify in fs/cifs/cifssmb.c to map the inotify flags to the flags available in the CIFS network protocol specifications.What about inotify makes it insufficient for your needs?
strongly agree, very strongly agree.What kind of real-world applications exist out there that need inotify
functionality, and what sort of requirements do they have (in particular
w.r.t. the notification mechanism)?
A few worksets:
- Current users, such as FAM and Samba, that need simple file
- Random applications that want to watch a file or two
- The Linux desktop
- Real-time live-updating indexing systems, such as Beagle,
that compete with f.e. Apple's Spotlight.
