| |
3.16.57-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Jan Chochol <jan@chochol.info>
commit cbebc6ef4fc830f4040d4140bf53484812d5d5d9 upstream.
Since commit 57e62324e469 ("NFS: Store the legacy idmapper result in the keyring") nfs_idmap_cache_timeout changed units from jiffies to seconds. Unfortunately sysctl interface was not updated accordingly.
As a effect updating /proc/sys/fs/nfs/idmap_cache_timeout with some value will incorrectly multiply this value by HZ. Also reading /proc/sys/fs/nfs/idmap_cache_timeout will show real value divided by HZ.
