Subject: NFS: Use dentry->d_time to store the parent directory verifier.
X-Git-Tag: v2.6.23-rc1~254^2~4
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=3062c532ad410fe0e8320566fe2879a396be6701

NFS: Use dentry->d_time to store the parent directory verifier.

This will free up the d_fsdata field for other use.
