Subject: xfs: remove the xlog_op_header_t typedef
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e478d8cf83cededd24d1c728fb6ce380ee4f9b5e;p=users%2Fhch%2Fmisc.git

xfs: remove the xlog_op_header_t typedef

Almost no users of the typedef left, kill it and switch the remaining
users to use the underlying struct.
