From: Bartlomiej Zolnierkiewicz Date: Fri, 27 Mar 2009 11:46:28 +0000 (+0100) Subject: ide: add "flagged" taskfile flags to struct ide_taskfile (v2) X-Git-Tag: upstream/snapshot3+hdmi~19886^2~46 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19710d25d50ae0be05eebe4231ed8918b1092d82;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git ide: add "flagged" taskfile flags to struct ide_taskfile (v2) * Add ->ftf_flags field to struct ide_taskfile and convert flags for TASKFILE ioctl to use it. * Rename "flagged" taskfile flags: - IDE_TFLAG_FLAGGED -> IDE_FTFLAG_FLAGGED - IDE_TFLAG_FLAGGED_SET_IN_FLAGS -> IDE_FTFLAG_SET_IN_FLAGS - IDE_TFLAG_{OUT,IN}_DATA -> IDE_FTFLAG_{OUT,IN}_DATA v2: * Remember to fully update ide-h8300.c, scc_pata.c and tx493{8,9}ide.c (thanks to Stephen Rothwell for noticing). There should be no functional changes caused by this patch.
