Subject: [SCSI] qla2xxx: Use msleep() as delay during ISP polling.
X-Git-Tag: v2.6.16-rc1~162^2~11
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=03ab2eabed74708c0c74163723007e8e72244219;p=linux-2.6

[SCSI] qla2xxx: Use msleep() as delay during ISP polling.

Mailbox commands are polled for completion during ISP
initialization.  During potentially 'long' mailbox commands
(i.e. fabric login), we really don't want a busy-wait delay
to potentially trigger a (benign) soft-lockup BUG().
