This patch contains the following linux kernel feature:
Summary: Dasd new function: fixed I/O buffers Description: This feature limits the number of pages referred by channel programs. It can be enabled by using a new keyword 'fixedbuffers' on the
'dasd=...'
parameter.
Example: dasd=7000-7002,fixedbuffers
When the new feature is enabled it applies to
PAGE_SIZE-formatted
ECKD disks, but not to disks that are accessed using the DIAG or FBA discipline. To check whether the parameter was recognized correctly you can check the boot messages.
When the fixed I/O buffers were enabled successfully you will find the following line in the log:
dasd: turning on fixed buffer mode
