In order to use the open-by-filehandle functionality with NFSv3, we
need to ensure that the NFS client can convert disconnected dentries
into connected ones by doing a reverse walk of the filesystem path.
To do so, NFSv4 provides the LOOKUPP operation, which does not
exist in NFSv3, but which can usually be emulated using lookup("..").
v2:
- Fix compilation issues for "NFSv3: Refactor nfs3_proc_lookup() to
split out the dentry"
v3:
- Fix the string length calculation
- Apply the NFS_MOUNT_SOFTREVAL flag in both the NFSv3 and NFSv4 lookupp
Trond Myklebust (3):
NFSv3: Refactor nfs3_proc_lookup() to split out the dentry
NFSv3: Add emulation of the lookupp() operation
NFSv4: Observe the NFS_MOUNT_SOFTREVAL flag in _nfs4_proc_lookupp
