Subject: nfs: convert setclientid and exchange_id encoders to use clp->cl_owner_id
X-Git-Tag: omap-for-v4.2/fixes-rc1^2~39^2~31
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3a6bb738792500e8b4534c0350c13a132bac0492;p=pandora-kernel.git

nfs: convert setclientid and exchange_id encoders to use clp->cl_owner_id

...instead of buffers that are part of their arg structs. We already
hold a reference to the client, so we might as well use the allocated
buffer. In the event that we can't allocate the clp->cl_owner_id, then
just return -ENOMEM.

Note too that we switch from a GFP_KERNEL allocation here to GFP_NOFS.
It's possible we could end up trying to do a SETCLIENTID or EXCHANGE_ID
in order to reclaim some memory, and the GFP_KERNEL allocations in the
existing code could cause recursion back into NFS reclaim.
