For luminous and beyond we are encoding the actual spgid, which requires operating with the correct pg_num, i.e. that of the target pool. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

need_check_tiering logic doesn't make a whole lot of sense. Drop it and apply tiering unconditionally on every calc_target() call instead. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

Otherwise we may miss events like PG splits, pool deletions, etc when we get multiple incremental maps at once. Because check_pool_dne() can now be fed an unlinked request, finish_request() needed to be taught to handle unlinked requests. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

When processing a map update consisting of multiple incrementals, we may end up running check_linger_pool_dne() on a lingering request that was previously added to need_resend_linger list. If it is concluded that the target pool doesn't exist, the request is killed off while still on need_resend_linger list, which leads to a crash on a NULL lreq->osd in kick_requests(): libceph: linger_id 18446462598732840961 pool does not exist BUG: unable to handle kernel NULL pointer dereference at 0000000000000010 IP: ceph_osdc_handle_map+0x4ae/0x870 Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

Give upper layers a chance to reencode the message after the connection is negotiated and ->peer_features is set. OSD client will use this to support both luminous and pre-luminous OSDs (in a single cluster): the former need MOSDOp v8; the latter will continue to be sent MOSDOp v4.

The old (v15) pi->last_force_request_resend has been repurposed to make pre-RESEND_ON_SPLIT clients that don't check for PG splits but do obey pi->last_force_request_resend resend on splits.

Current code does not update ceph_dentry_info::lease_session once it is set. If auth mds of corresponding dentry changes, dentry lease keeps in an invalid state.

Current ceph uses FSID as primary index key of fscache data. This allows ceph to retain cached data across remount. But this causes problem (kernel opps, fscache does not support sharing data) when a filesystem get mounted several times (with fscache enabled, with different mount options). The fix is adding a new mount option, which specifies uniquifier for fscache.

Previously we were returning values for quota, layout xattrs without any kind of update -- the user just got whatever happened to be in our cache. Clearly this extra round trip has a cost, but reads of these xattrs are fairly rare, happening on admin intervention rather than in normal operation.

Pull MIPS fixes from Ralf Baechle: "Here's a final round of fixes for 4.12: - Fix misordered instructions in assembly code making kenel startup via UHB unreliable. - Fix special case of MADDF and MADDF emulation. - Fix alignment issue in address calculation in pm-cps on 64 bit. - Fix IRQ tracing & lockdep when rescheduling - Systems with MAARs require post-DMA cache flushes. The reordering fix and the MADDF/MSUBF fix have sat in linux-next for a number of days. The others haven't propagated from my pull tree to linux-next yet but all have survived manual testing and Imagination's automated test system and there are no pending bug reports" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Avoid accidental raw backtrace MIPS: Perform post-DMA cache flushes on systems with MAARs MIPS: Fix IRQ tracing & lockdep when rescheduling MIPS: pm-cps: Drop manual cache-line alignment of ready_count MIPS: math-emu: Handle zero accumulator case in MADDF and MSUBF separately MIPS: head: Reorder instructions missing a delay slot

uapi/linux/a.out.h uses a number of predefined macros that are deprecated because they're in the application namespace (e.g. '#ifdef linux' instead of '#ifdef __linux__'). This patch either corrects or just removes them if they are not applicable to Linux. The primary reason this is worth bothering to fix, considering how obsolete a.out binary support is, is that the GCC build process considers this such a severe error that it will copy the header into a private directory and change the macro names, which causes future updates to the header to be masked. This header probably doesn't get updated very often anymore, but it is the _only_ uapi header that gets this treatment, so IMHO it is worth patching just to drive that number all the way to zero.
