I know that dentries and inodes for regular filesystems can be discarded from RAM if they're not in use, is that the case for a tmpfs? How often are the files in /var/run and /var/lock accessed? Is the kernel likely to discard them? Files in /var/run tend to be 4 or 5 bytes in length, does that mean they each use an entire page of RAM or swap? There are vastly fewer swap pages than there are filesystem blocks, isn't this less efficient? -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
