[PATCH] FUSE: tighten check for processes allowed access
This patch tightens the check for allowing processes to access non-privileged mounts. The rational is that the filesystem implementation can control the behavior or get otherwise unavailable information of the filesystem user. If the filesystem user process has the same uid, gid, and is not suid or sgid application, then access is safe. Otherwise access is not allowed unless the "allow_other" mount option is given (for which policy is controlled by the userspace mount utility). Thanks to everyone linux-fsdevel, especially Martin Mares who helped uncover problems with the previous approach.
