Hi Frédéric,

Today's linux-next merge of the bkl-ioctl tree got a conflict in
fs/proc/inode.c between commit 3ab8dfb0802f33741cc4afa6adf7cb30b1cd1761
("procfs: Kill the bkl in ioctl") from the bkl-procfs tree and commit
1dd97d3d546aa14db7efa5366b21d1336b91379e ("Rename 'struct
file_operations' 'ioctl' fn pointer to 'bkl_ioctl'") from the bkl-ioctl

I fixed it up (see below - probably not optimal) and can carry the fix as
