Subject: [PATCH] nfsroot: make nfsroot to accept the 1024 bytes long directory name
Date: Thu, 24 Sep 2015 10:19:09 +0800 [thread overview]
Message-ID: <1443061149-25153-1-git-send-email-roy.qing.li@gmail.com> (raw)
From: Li RongQing <roy.qing.li@gmail.com>
although NFS_MAXPATHLEN is defined to 1024, nfs client hopes to accept
a 1024 byte path, but nfs_root_parms is limited to 256, and the nfs path
will truncated when a user inputs nfs path from kernel cmdline
enlarge nfs_root_parms to 1024, to make it accept the 1024 bytes long
directory name, since nfs_root_parms is defined as _initdata, it will
be released after system bootup
