libceph: bump CEPH_MSG_MAX_DATA_LEN

2018-11-22T06:32:46+00:00

commit 94e6992bb560be8bffb47f287194adf070b57695 upstream.

If the read is large enough, we end up spinning in the messenger:

  libceph: osd0 192.168.122.1:6801 io error
  libceph: osd0 192.168.122.1:6801 io error
  libceph: osd0 192.168.122.1:6801 io error

This is a receive side limit, so only reads were affected.

libceph: use BUG() instead of BUG_ON(1)

2017-04-18T05:55:49+00:00

commit d24cdcd3e40a6825135498e11c20c7976b9bf545 upstream.

I ran into this compile warning, which is the result of BUG_ON(1)
not always leading to the compiler treating the code path as
unreachable:

    include/linux/ceph/osdmap.h: In function 'ceph_can_shift_osds':
    include/linux/ceph/osdmap.h:62:1: error: control reaches end of non-void function [-Werror=return-type]

Using BUG() here avoids the warning.

libceph: introduce ceph_osdc_cancel_request()

2014-07-08T11:08:44+00:00

Introduce ceph_osdc_cancel_request() intended for canceling requests
from the higher layers (rbd and cephfs).  Because higher layers are in
charge and are supposed to know what and when they are canceling, the
request is not completed, only unref'ed and removed from the libceph
data structures.

__cancel_request() is no longer called before __unregister_request(),
because __unregister_request() unconditionally revokes r_request and
there is no point in trying to do it twice.
