[redhat] New configs in drivers/md
Hi,
As part of the ongoing rebase effort, the following configuration options need to be reviewed.
As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy.
If the value for a file that is added should be changed, please reply with a better option.
CONFIG_DM_EBS:
dm-ebs emulates smaller logical block size on backing devices with larger ones (e.g. 512 byte sectors on 4K native disks).
Symbol: DM_EBS [=n] Type : tristate Defined at drivers/md/Kconfig:340 Prompt: Emulated block size target (EXPERIMENTAL) Depends on: MD [=y] && BLK_DEV_DM [=m] Location: -> Device Drivers -> Multiple devices driver support (RAID and LVM) (MD [=y]) -> Device mapper support (BLK_DEV_DM [=m]) Selects: DM_BUFIO [=m]
CONFIG_DM_MULTIPATH_HST:
This path selector is a dynamic load balancer which selects the path expected to complete the incoming I/O in the shortest time by comparing estimated service time (based on historical service time).
If unsure, say N.
Symbol: DM_MULTIPATH_HST [=n] Type : tristate Defined at drivers/md/Kconfig:455 Prompt: I/O Path Selector based on historical service time Depends on: MD [=y] && DM_MULTIPATH [=m] Location: -> Device Drivers -> Multiple devices driver support (RAID and LVM) (MD [=y]) -> Device mapper support (BLK_DEV_DM [=m]) -> Multipath target (DM_MULTIPATH [=m])
