scsi: mpi3mr: Support for preallocation of SGL BSG data buffers (!4364) · Merge requests · Red Hat / centos-stream / src / kernel / centos-stream-9

Ewan D. Milne requested to merge e-milne/centos-stream-9:RHEL-18205 into main May 29, 2024

JIRA: https://issues.redhat.com/browse/RHEL-18205 Upstream Status: From upstream linux mainline

The driver now supports SGLs for BSG data transfer. Upon loading, the driver pre-allocates SGLs in chunks of 8k, results in a total of 256 * 8k, equal to 2MB. These pre-allocated SGLs are reserved for handling BSG commands and are deallocated during driver unload.
