- This turns on a logging facility.
+ This option allows you to specify the maximum number of scatter-
+ gather entries per I/O. The driver default is 128, which matches
+ MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this
+ can be 256. However, it may decreased down to 16. Decreasing this
+ parameter will reduce memory requirements on a per controller instance.
