Hi guys, For fun and learning purposes I'm trying to add an mountflag for NFS-mounts to the kernel and mount. The flag's semantics are identical to ac/noac: 'flag' is default but has no special meaning, 'noflag' triggers a certain action. I have a small question about adding the flag to include/linux/nfs_mount.h. Since NFS_MOUNT_FLAGMASK is defined as 0xFFFF, and all bits up until 0xFFFF are occupied by existing NFS_MOUNT-flags, how could I add my own flag? Would it be ok to define NFS_MOUNT_FLAGMASK as 0xFFFFF and my own flag as 0x10000? Or will this have other side effects? It seems to be working though ;-). How would this be done if a real flag should be added by kernel maintainers? I guess another option would be to create a new entry in the nfs_mount_data struct and treat it as an option (rsize-, wsize-, timeo-alike), but I'd like to do keep it the same as other flags. Please advice! ;-) Thanks in advance for your time.
