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:

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.
