Hi all,
Today's linux-next merge of the userns tree got a conflict in:
arch/x86/kernel/process.c
between commit:
3a24a60854d2 ("x86/32: Remove lazy GS macros")
from the tip tree and commit:
5bd2e97c868a ("fork: Generalize PF_IO_WORKER handling")
from the userns tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
