Hi Jens,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

block/cfq-iosched.c: In function 'cfq_init_queue':
block/cfq-iosched.c:3690:14: error: 'cic_index_lock' undeclared (first use in this function)
block/cfq-iosched.c:3691:15: error: 'cic_index_ida' undeclared (first use in this function)
block/cfq-iosched.c:3691:34: error: 'struct cfq_data' has no member named 'cic_index'

Presumably this was not build tested with CONFIG_CFQ_GROUP_IOSCHED set.

Caused by commit a73f730d013f ("block, cfq: move cfqd->cic_index to
q->id") interacting with commit 2984ff38ccf6 ("cfq-iosched: free
cic_index if blkio_alloc_blkg_stats fails").

I have used the block tree from next-20111215 for today.
