From: Matt Fleming <matt.fleming@xxxxxxxxx> drivers/firmware/efivars.c has grown pretty large and is ~2K lines. Inside efivars.c there's currently, o code for handling EFI variables at the firmware-level o sysfs code for exposing EFI variables o a new EFI variable filesystem o a persistent storage backend all intertwined and smushed together. This situation is only going to get worse as new EFI support is added. We need an interface that hides the EFI variable operations in use so code isn't tempted to access them directly, e.g. efivarfs currently uses '__efivars' which means it doesn't work for CONFIG_GOOGLE_SMI as that uses different variable ops. With this interface in place, we can start moving independent code out into separate files, allowing users to only turn on the functionality that they want. This patch series introduces the new efivar_entry API, and splits out the major parts of efivars.c into new files. There's more work TODO, but this is at least a start. The series is also available on the 'chainsaw' branch at, git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/linux.git Comments welcome.
