[PATCH-RFC-RESEND 8/9] nfsd: Pass filehandle to nfs4_preprocess_stateid_op()
From: Peng Tao <hidden>
Date: 2015-08-26 08:16:49
Also in:
linux-fsdevel, linux-nfs
Subsystem:
filesystems (vfs and infrastructure), kernel nfsd, sunrpc, and lockd servers, the rest · Maintainers:
Alexander Viro, Christian Brauner, Chuck Lever, Jeff Layton, Linus Torvalds
From: Anna Schumaker <redacted> This will be needed so COPY can look up the saved_fh in addition to the current_fh.
