* SUNRPC: Fix the NFSv4 and RPCSEC_GSS Kconfig dependenciesTrond Myklebust2010-09-12
| | | | | | | | | | | | | | | The NFSv4 client's callback server calls svc_gss_principal(), which is defined in the auth_rpcgss.ko The NFSv4 server has the same dependency, and in addition calls svcauth_gss_flavor(), gss_mech_get_by_pseudoflavor(), gss_pseudoflavor_to_service() and gss_mech_put() from the same module. The module auth_rpcgss itself has no dependencies aside from sunrpc, so we only need to select RPCSEC_GSS.

* Remove EXPERIMENTAL from NFS_FSCACHEChristian Kujau2010-02-26
| | | | | | | | | | | | | | | | | | There's currently an open Ubuntu bug[0], with the intent to compile NFS_FSCACHE (and possibly AFS_FSCACHE, 9P_FSCACHE) into the standard Ubuntu kernel. However, since *_FSCACHE still depends on EXPERIMENTAL, this won't happen. As Arjan van de Ven pointed out[1], the EXPERIMENTAL flag doesn't mean that much any more, I propose the following patch to fs/nfs/Kconfig. I'd do the same for fs/9p/Kconfig and fs/afs/Kconfig, but as I did not test 9p or AFS, I feel it would not be appropriate for me to remove the flag.

| * lockd: fix FILE_LOCKING=n build errorRandy Dunlap2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lockd/svclock.c is missing a header file <linux/fs.h>. <linux/fs.h> is missing a definition of locks_release_private() for the config case of FILE_LOCKING=n, causing a build error: fs/lockd/svclock.c:330: error: implicit declaration of function 'locks_release_private' lockd without FILE_LOCKING doesn't make sense, so make LOCKD and LOCKD_V4 depend on FILE_LOCKING, and make NFS depend on FILE_LOCKING.
