Subject: NFS: Read requests can use GFP_KERNEL.
X-Git-Tag: v2.6.35-rc1~490^2~10
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=93870d76fee22e887aa6e7e1fc904dbeca976928;p=karo-tx-linux.git

NFS: Read requests can use GFP_KERNEL.

There is no danger of deadlock should the allocation trigger page
writeback.
