linux-next: manual merge of the akpm-current tree with the vfs tree

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

 



Hi Andrew,

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

  lib/vsprintf.c

between commit:

  1031bc589228 ("lib/vsprintf: add %*pg format specifier")

from the vfs tree and commit:

  88f2367418d7 ("mm, printk: introduce new format string for flags")

from the akpm-current tree.

I fixed it up (I switched the latter to 'j' since there were less of
them to fix up - see below) and can carry the fix as necessary (no action
is required).

I also added this patch to fix up all the new uses.
