    Hello all,

            Just upgraded to 2.3.51 earlier today. In the course of plugging
    in a suggestion from Linus concerning shmget errors (mounting shm file
    system DID fix that problem) I noticed a rather strange anomoly. File
    systems which use to NOT show up with "df" now do show up with wierd numbers.

    ] [root@alcove mhw]# df

    ] /dev/sda1 132207 64192 61189 51% /

    ] [root@alcove mhw]#

            Before (2.3.50 and earlier) this would never have shown the "none"
    entries or the "automount" entries.

            BTW... Is it just me or does it seem like we've recently aquired
    a lot of new "none" type file systems (pts, usbfs, devfs, shm, etc)? I
    know proc and pts have been around for a while, it just seems like I've
    had to add a bunch of new ones to fstab in the last couple of months. Is
    this a new paradgm to add special purpose file systems?

            Mike
