Subject: [PATCH] libata: change order of _SDD/_GTF execution (resend #3)
X-Git-Tag: v2.6.21-rc1~73^2~1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=08573a86c8da1379b4f341ab4781bb7c8685d5b6;p=linux-2.6

[PATCH] libata: change order of _SDD/_GTF execution (resend #3)

Make the sdd call come before gtf.  _SDD is used to provide
input to the _GTF file, so it should be executed first.
