Hi Linus,

A few fixes in here, all based on reports and test cases from folks
using it. Most of it is stable material as well.

- Hashed work cancelation fix (Pavel)

- poll wakeup signalfd fix

- memlock accounting fix

- nonblocking poll retry fix

- Ensure we never return -ERESTARTSYS for reads

- Ensure offset == -1 is consistent with preadv2() as documented

- IOPOLL -EAGAIN handling fixes

- Remove useless task_work bounce for block based -EAGAIN retry 

Please pull!
