doc/dev: refresh vstart.sh options in dev_cluster_deployment
Bring doc/dev/dev_cluster_deployment.rst back in line with the current
src/vstart.sh:
* drop the removed -K/--kstore objectstore backend
* drop -N/--not-new, which was dropped in 8dd2e418; reusing the existing
cluster config is simply the default when -n is not given
* correct the --rgw_frontend default from civetweb to beast
* note that -b/--bluestore is the default objectstore backend
* update the example and add a note that a fresh build needs -n on the
first run, while later runs can omit it
* note that the option list is not exhaustive and point at src/vstart.sh

doc/rados/configuration: recommend wpq for EC clusters seeing slow ops
On large EC clusters, mClock currently routes recovery EC sub-reads
through the immediate queue, skipping throttling. When many OSDs read
from one source during recovery, that source's high-priority queue
saturates and starves client work, producing slow ops. Recommend
falling back to wpq in the mClock config reference until the
scheduler treats those reads as background.

Add documentation warnings explaining that all RGW daemons and

Mismatched shard counts cause writes and reads/trim to target different

debian: drop explicit libprotobuf dependency from ceph-osd-crimson
The ceph-osd-crimson package already lists ${shlibs:Depends} in its
Depends field, which generates the correct libprotobuf dependency for

Trixie/Noble). The hardcoded libprotobuf23 entry is redundant and
breaks installations on distributions where protobuf ships under a
different package name.

crimson: use uint32_t when calling ioctl(BLKGETNRZONES)
before this change, we pass a pointer to a `size_t` to
ioctl(BLKGETNRZONES), but in the Linux kernel,
include/uapi/linux/blkzoned.h:
```c
#define BLKGETNRZONES _IOR(0x12, 133, __u32)
```
this API reads 32 bits of data into the pointer. on 64-bit
architectures, size_t is 64 bits. fortunately, we initialize
nr_zones with 0, so the upper 32 bits remain zero. this works
on little-endian systems, but not on big-endian systems. it is
also semantically wrong. we should pass a pointer to a 32-bit
value when calling ioctl(BLKGETNRZONES).
in this change, we change the type of nr_zones from size_t to
uint32_t to match what the Linux kernel expects.
