[PATCH 2.6.12-rc4-mm1 1/4] megaraid_sas: updating the driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello All,

Please review this update to the previously submitted megaraid_sas driver.
I have adopted all the feedback received for the initial submission. Since
most of the code is rearranged, I have split the patches into four parts - 
the first two remove the original code and the second two add the new code.

Thank you,
Sreenivas Bagalkote

Patch 1 of 4:
