[PATCH RFC] module-setup.sh: install usb serial driver for ttyUSB0

by Dave Young

In case one want to use usb serial console, we need to pack the usb serial driver into kdump initramfs so that one can see the console output on the usb console. I only handled ttyUSB0, this is like a hard code, but it should be enough for most cases. Also only install the driver for the ttyUSB0 device. Tested with adding "console=ttyUSB0" in 2nd kernel commandline. Tested latest F22 kernel, there's CONFIG_USB_SERIAL_CONSOLE=y, kdump work ok.

[PATCH] dracut-module-setup: Mute the error message when kdump detects iSCSI session by iscsiadm

by Minfei Huang

For independent hardware iSCSI HBA, the network config will be recorded in the firmware BIOS. It fails to use normal means(like iscsiadm) to detect iSCSI session details, since HBA firmware doesn't expose the session to running kernel. Mute the error message when kdump detects iSCSI session by iscsiadm.

[PATCH v2] kdump.sysconfig: add KDUMP_COMMANDLINE_REMOVE

Use KDUMP_COMMANDLINE_REMOVE config instead of hardcode them in kdumpctl. System admins can also specify what to remove as they like.

[PATCH RFE] kdump.sysconfig: Support KDUMP_COMMANDLINE_REMOVE

Some parameters need to be removed from the cmdline when kdump. These include "quiet", "slub_debug", etc. This patch allows system admins to config what to remove, since they may use a different kernel. What about some existing params?

"quiet" will disable most of log messages. Since kdump is somehow unsteady and a rare condition, it's better to enable more logs.
