Re: linux-next: build failure after merge of the net-next tree

Hi all,

This was not actually the net-next tree (except that the net-next tree
was updated before I merged it to include a whole new section of Linus'
tree after Linus merged the net-next tree).  Sorry about that.

Hi all,

After merging the net-next tree, today's linux-next build (X86_64
allnoconfig) failed like this:

Caused by commit

  342f43af70db ("iscsi_ibft: fix crash due to KASLR physical memory remapping")

Unfortunately that commit has now been merged into Linus' tree as well.

And. unfortunately, that commit had not been in linux-next until today.
