This patch enables reading the amount of inotify watches in use. Inotify watches are a finite resource, in a similar way to available file descriptors. However, there is no way to check how many watches we have available or in use, we can only read the max.
This patch adds a 'current_inotify_watches' entry to the per-user sysctl table that gets mounted under /proc/sys/user/. This is the same table that contains 'max_inotify_watches'. The motivation for this patch is to be able to set up monitoring and alerting before an application starts failing because it runs out of inotify watches.
