Subject:  OpenAFS gatekeepers request addition of AFS_SUPER_MAGIC to magic.h


Hello,

Jeffrey Altman, one of the gatekeepers of OpenAFS (the open source
project which inherited the Transarc/IBM AFS codebase) has requested
that the magic number 0x5346414F (little endian 'OAFS') be allocated
for the f_type field of the fsinfo structure on Linux:

  https://lists.openafs.org/pipermail/openafs-info/2006-December/024829.html

I would like to offer the patch below for inclusion in the source
tree, if possible.  The patch adds it to include/linux/magic.h, mostly
as a way of publishing this number and ensuring that no other
filesystem accidentally uses it.
