| |
hello, Rusty: I encountered a problem when modules compiled built-in with bzImage:
open-iscsi is an iSCSI software, it has a userspace daemon(iscsid) and a userspace mani tool(iscsiadm) and a kernel module (scsi_transport_iscsi), recently the kernel module has been accepted into the official kernel release; since the module licensed with GPL, it could be compiled as built-in,
but when I compiled the module within the bzImage, the problem appeared:
tux ~ # iscsid -f iscsid: Missing or Invalid version from /sys/module/scsi_transport_iscsi/version. Make sure a up to date scsi_transport_iscsi module is loaded and a up todate version of iscsid is running. Exiting...
this is just because iscsid hope there's an external module could be under /sys/module, and read the kernel module's version information, but if the module compiled built-in, all its module information discarded and it doesn't appeared under /sys/module/, that would break iscsid.
Now the problem is:
Should we provide module information under /sys/module/<module-name>/... even if the module compiled built-in with bzImage? Or just this module(scsi_transport_iscsi) should be marked with [M] only?
if the former solution is preferred, I would be happy to work on MODULE_INFO-like macros improvements with CONFIG_MODULE undefined.
