Take an extra reference on a device insert. So devices keep around in the cache until nfs_client release. (This was the behaviour of the old cache) The extra reference will be removed in nfs4_deviceid_purge_client(). I tested this and it works perfectly. TODO: Define an nfs4_get_deviceid() Currently accessing did->ref directly TODO: nfs4_insert_deviceid_node should check if there are too many devices and start purging them. Say by longest time from last use. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> --- fs/nfs/objlayout/objio_osd.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-)
