Hi,
This is a second go at this patch. I believe that I've fixed
the main problem with the last version which caused sparc to
fail to compile. I don't have a sparc to test with though, so
I'll have to leave that to others to test, I'm afraid.
Unlike the previous version, I've put the "const" by the individual
variable declarations, all aside from the nfsroot one that is
which was the cause of the problems. That is marked as __initconst
instead.
This patch is against linux-next, but it should apply ok against
current upstream as well, modulo a few offsets in the lines.
Is this trivial enough for the trivial tree, or is there a better
place for it, VFS tree, or direct into linux-next for example?
