Hello Ming, From the MAINTAINERS file: SCSI SUBSYSTEM M: "James E.J. Bottomley" <[email protected]> T: git git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git M: "Martin K. Petersen" <[email protected]> T: git git://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git L: [email protected] S: Maintained F: Documentation/devicetree/bindings/scsi/ F: drivers/scsi/ F: include/scsi/ Hence my surprise when I saw that you sent this patch series to Jens instead of James and Martin? Bart.
