[Michael Reed (mreed8855)]

Out of above patches below these patches are the ones which are not specific to MR only but many drivers are modified(to use new kernel APIs in place of older APIs) and megaraid_sas is one of those drivers-

8b904b5 block: Use blk_queue_flag_*() in drivers instead of queue_flag_*()

a9a0884 vfs: do bulk POLL* -> EPOLL* replacement

afc9a42 the rest of drivers/*: annotate ->poll() instances

@Michael_Reed,
If these patches are not backported in time for the .1 iso... it becomes a huge problem because these patches are required for install.

Is this work being tracked in another launchpad?
