Hi James,
One of the customer had reported that the set of raid logical arrays will
become unavailable (I/O offline) after a long hours of IO stress test. The OS
wouldn`t be accessible afterwards and require a hard reset.
This driver patch has a fix for race condition between the doorbell and
This patch set introduces sg_pcopy_from_buffer() and sg_pcopy_to_buffer(),
which copy data between a linear buffer and an SG list.
The only difference between sg_pcopy_{from,to}_buffer() and
sg_copy_{from,to}_buffer() is an additional argument that specifies
the number of bytes to skip the SG
This function is used to proceed page iterator to the next page if
necessary, and will be used to implement the variants of
sg_copy_{from,to}_buffer() later.

the number of bytes to skip the SG list before copying.
