Subject: [CIFS] Prevent OOPs when mounting with remote prefixpath.
X-Git-Tag: v2.6.29-rc6~15^2~6
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e4cce94c9c8797b08faf6a79396df4d175e377fa;p=pandora-kernel.git

[CIFS] Prevent OOPs when mounting with remote prefixpath.

Fixes OOPs with message 'kernel BUG at fs/cifs/cifs_dfs_ref.c:274!'.
Checks if the prefixpath in an accesible while we are still in cifs_mount
and fails with reporting a error if we can't access the prefixpath

Should fix Samba bugs 6086 and 5861 and kernel bug 12192
