X-Git-Tag: v2.6.18-rc1~1079^2~98^2~8
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dedaf2b0365ccec50714fbde0b3215e7e94fa47c;p=pandora-kernel.git

[PATCH] libata-ncq: implement ap->qc_active, ap->sactive and complete helper

Add ap->qc_active and ap->sactive, mask of all active qcs and libata's
view of the SActive register, respectively.  Also, implement
ata_qc_complete_multiple() which takes new qc_active mask and complete
multiple qcs according to the mask.

These will be used to track NCQ commands and complete them.  The
distinction between ap->qc_active and ap->sactive is also useful for
later PM implementation.
