Subject: libxfs: add fsxattr flags and fields for cowextsize
X-Git-Tag: v4.9.0-rc1~57
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1bc58d9361602943b9f729d7ea01ef3c88d6b172;p=thirdparty%2Fxfsprogs-dev.git

libxfs: add fsxattr flags and fields for cowextsize

Add the cowextsize field and flag to each platform's struct fsxattr
definitions.  We can compile these definitions into the xfsprogs
utilities if we don't pick them up from the system headers, such as on
kernels prior to 4.9.
