Yet another revised version of the sparse read patches. The first 4 and
last patch are essentially the same as the ones I posted earlier this
week, modulo a couple of small changes. Patches 5 and 6 add support for
sparse reads to ms_mode=secure and ms_mode=legacy mounts.

This series is necessary for the fscrypt integration work. In fact, I
was able to run the fscrypt series I posted earlier this week on top of
this and it worked just fine.

Again, I'm mostly looking for feedback from Ilya at this point, but I'll
probably go ahead and merge this into the testing branch later today
(unless anyone pipes up with objections).

Jeff Layton (7):
  libceph: add spinlock around osd->o_requests

  libceph: add sparse read support to OSD client
  libceph: support sparse reads on msgr2 secure codepath
  libceph: add sparse read support to msgr1
  ceph: add new mount option to enable sparse reads
