Amir, what > are your thoughts on this? I think that the mention of inotify vs. fanotify features in fanotify.7 man page is decent - if anyone wants to improve it I won't mind. A mention of fanotify as successor in inotify.7 man page is not a bad idea - patches welcome. As to MAINTAINERS, I think that 'Maintained' feels right. We may consider 'Odd Fixes' for inotify and certainly for 'dnotify', but that sounds a bit too harsh for the level of maintenance they get. I'd like to point out that IMO, man-page is mainly aimed for the UAPI users and MAINTAINERS is mostly aimed at bug reporters and drive-by developers who submit small fixes. When developers wish to add a feature/improvement to a subsystem, they are advised to send an RFC with their intentions to the subsystem maintainers/list to get feedback on their design before starting to implement. Otherwise, the feature could be NACKed for several reasons other than "we would rather invest in the newer API". Bottom line - I don't see a strong reason to change anything, but I also do not object to improving man page nor to switching to 'Odd Fixes' status. Thanks, Amir.
