linux-next: manual merge of the tty tree with Linus' tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Today's linux-next merge of the tty tree got a conflict in:

  drivers/tty/vt/selection.c

between commits:

  4b70dd57a15d ("vt: selection, push console lock down")
  e8c75a30a23c ("vt: selection, push sel_lock up")

from Linus' tree and commits:

  9256d09f1da1 ("vt: selection, create struct from console selection globals")
  bc80932cc25a ("vt: selection, indent switch-case properly")

from the tty tree.

I fixed it up (I think - 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.
