Subject: fs/xfs: Use the enum req_op and blk_opf_t types
X-Git-Tag: v6.0-rc1~178^2~25
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d03025aef8676e826b69f8e3ec9bb59a5ad0c31d;p=tomoyo%2Ftomoyo-test1.git

fs/xfs: Use the enum req_op and blk_opf_t types

Improve static type checking by using the enum req_op type for variables
that represent a request operation and the new blk_opf_t type for the
combination of a request operation with request flags.
