Subject: [PATCH] NFSv4: fix mount segfault on errors returned that are < -1000
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c12e87f4652b1ba3be168b4f63a440399b941928;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[PATCH] NFSv4: fix mount segfault on errors returned that are < -1000

It turns out that nfs4_proc_get_root() may return raw NFSv4 errors instead of
mapping them to kernel errors.  Problem spotted by Neil Horman
