Subject: [SCSI] Don't attempt to send extended INQUIRY command if
|
||||
skip_vpd_pages is set
|
||||
Origin: https://git.kernel.org/cgit/linux/kernel/git/jejb/scsi.git/commit?id=7562523e84ddc742fe1f9db8bd76b01acca89f6b
|
||||
Bug-Debian: http://bugs.debian.org/719002
|
||||
|
||||
If a device has the skip_vpd_pages flag set we should simply fail the
|
||||
scsi_get_vpd_page() call.
