From f9b60e2209213fdfcc504ba25a404977c5d08b77 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 16 Apr 2021 14:00:15 -0400 Subject: nfsd: hash nfs4_files by inode number The nfs4_file structure is per-filehandle, not per-inode, because the spec requires open and other state to be per filehandle. But it will turn out to be convenient for nfs4_files associated with the same inode to be hashed to the same bucket, so let's hash on the inode instead of the filehandle. Filehandle aliasing is rare, so that shouldn't have much performance impact. (If you have a ton of exported filesystems, though, and all of them have a root with inode number 2, could that get you an overlong hash chain? Perhaps this (and the v4 open file cache) should be hashed on the inode pointer instead.) Signed-off-by: J.
