Subject[ANNOUNCE] megaraid 2.00.6 driver
Date
Announcing megaraid 2.00.6 driver release. This can be downloaded from the
following location:

ftp://ftp.lsil.com/pub/linux-megaraid/drivers/version-2.00.6/

Changes in 2.00.6 from 2.00.5 driver:

1. Changes suggested by Tomita Haruo - Wait for valid status in mailbox.
2. Changes suggested by Mark Haverkamp - Move /proc related code fragments
under #ifdef CONFIG_PROC_FS directives.
3. /proc changes required to correctly display logical drive information for
drives on some older controllers. (Eg., Express 200, 466)
