Subject: [PATCH] fastboot: remove "wait for all devices before mounting root" delay
|
|
Patch-mainline: not yet
|
|
|
|
In the non-initrd case, we wait for all devices to finish their
|
|
probing before we try to mount the rootfs.
|
|
In practice, this means that we end up waiting 2 extra seconds for
|
|
the PS/2 mouse probing even though the root holding device has been
|
|
ready since a long time.
|
|
|
|
The previous two patches in this series made the RAID autodetect code
|
|
do it's own "wait for probing to be done" code, and added
|
|
"wait and retry" functionality in case the root device isn't actually
|
|
available.
|
|
|
|
These two changes should make it safe to remove the delay itself,
|
|
and this patch does this. On my test laptop, this reduces the boot time
|
|
by 2 seconds (kernel time goes from 3.9 to 1.9 seconds).
