Subject: SMB3: Fix mkdir when idsfromsid configured on mount
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c8c412f976124d85b8ded85c6ac3f760c12b63a3;p=linux.git

SMB3: Fix mkdir when idsfromsid configured on mount

mkdir uses a compounded create operation which was not setting
the security descriptor on create of a directory. Fix so
mkdir now sets the mode and owner info properly when idsfromsid
and modefromsid are configured on the mount.
