Subject: add support for dirsync mount option
X-Git-Tag: lxc-0.7.4-rc1~37
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=968fbd36057db3132c68a63700e42929e5df5e2d;p=thirdparty%2Flxc.git

add support for dirsync mount option

Add support for `dirsync' mount option. MS_DIRSYNC is on of the
mount(2) mountflags so don't send it as extra mount option to avoid:

 	lxc-start: Invalid argument - failed to mount ...

errors.
