whenever you want), say M here and read
<file:Documentation/modules.txt>. The module will be called coda.
config CODA_FS_OLD_API
bool "Use 96-bit Coda file identifiers"
depends on CODA_FS
help
A new kernel-userspace API had to be introduced for Coda v6.0
to support larger 128-bit file identifiers as needed by the
new realms implementation.
However this new API is not backward compatible with older
clients. If you really need to run the old Coda userspace
cache manager then say Y.
For most cases you probably want to say N.
config INTERMEZZO_FS
