Subject: NFS: Use kzalloc() instead of kmalloc() in the idmapper
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=57a51048da742c764b6ce5d028c7f334ae04d363;p=linux-beck.git

NFS: Use kzalloc() instead of kmalloc() in the idmapper

This will allocate memory that has already been zeroed, allowing us to
remove the memset later on.
