Subject: [PATCH 002 of 8] knfsd: nfsd4: fix NFSv4 filehandle size units confusion


From: "J. Bruce Fields" <bfields@...ldses.org>


NFS4_FHSIZE is measured in bytes, not 4-byte words, so much more space
than necessary is being allocated for struct nfs4_cb_recall.

I should have wondered why this structure was so much larger than it
needed to be!
