| |
Hi, Please find attached a replacement for linux/scripts/patch-kernel (The diff was larger than the file)
It adds a -ac option, so you can do
patch-kernel . .. 2.4.9 -ac
For example on a 2.4.x source tree and upgrade it to 2.4.9 and apply the latest ac patch in the patch directory.
or
patch-kernel . .. 2.4.9 -ac14
To use the -ac14 patch instead of the latest
or
patch-kernel . .. -ac
To upgrade to the latest Linus kernel and then apply the latest -ac patch for it.
I've given it a reasonably heavy test, but would welcome suggestions/comments.
One known issue is that:
patch-kernel . .. -ac 2.4.9
Is invalid and is not warned about (the base kernel version must be $3)
I also fixed a case where the stop version was checked too late.
Enjoy,
Dave
