However, CONFIG_AFS_FSCACHE still appears to be disabled at the moment:
~/ubuntu-quantal/debian.master/config$ grep -rn "CONFIG_AFS_FSCACHE" *
config.common.ubuntu:158:# CONFIG_AFS_FSCACHE is not set
Examining CONFIG_AFS_FSCACHE further, it appears it is marked as EXPERIMENTAL. ie:
~/ubuntu-quantal$ grep -A7 "config AFS_FSCACHE" fs/afs/Kconfig config AFS_FSCACHE
bool "Provide AFS client caching support (EXPERIMENTAL)"
depends on EXPERIMENTAL
depends on AFS_FS=m && FSCACHE || AFS_FS=y && FSCACHE=y
help
Say Y here if you want AFS data to be cached locally on disk through
the generic filesystem cache manager
Our default configuration policy is to disable EXPERIMENTAL options until there has been a specific request to enable them and the requested option would result in minimal risk of regression/negative impact. I've subsequently applied the attached patch which enables CONFIG_AFS_FSCACHE=y to the Quantal kernel repo. Thanks.
For the Quantal 12.10 kernel, it appears that the following are already enabled:
~/ubuntu- quantal/ debian. master/ config$ grep -rn "CONFIG_ NFS_FSCACHE" * common. ubuntu: 3749:CONFIG_ NFS_FSCACHE= y
config.
~/ubuntu- quantal/ debian. master/ config$ grep -rn "CONFIG_ CIFS_FSCACHE" * common. ubuntu: 871:CONFIG_ CIFS_FSCACHE= y
config.
However, CONFIG_AFS_FSCACHE still appears to be disabled at the moment:
