V2:
- print the client global id for all the dout()/pr_warn(),etc.
This is based the testing branch.
Xiubo Li (6):
ceph: add the *_client debug macros support
ceph: pass the mdsc to several helpers
ceph: rename _to_client() to _to_fs_client()
ceph: move mdsmap.h to fs/ceph/
ceph: add ceph_inode_to_client() helper support
ceph: print the client global_id in all the debug logs

Hi Xiubo,
There is a related concern that clients can belong to different
clusters, in which case their global IDs might clash. If you chose
to disregard that as an unlikely scenario, it's probably fine, but
it would be nice to make that explicit in the commit message.
If account for that, the identifier block could look like:
[<cluster fsid> <gid>]
instead of:
[client.<gid>]
The "client." string prefix seems a bit redundant since the kernel
client's entity is always CEPH_ENTITY_TYPE_CLIENT. If you like it
anyway, I would at least get rid of the dot at the end to align with
how it's presented elsewhere (e.g. debugfs directory name or
"ceph.client_id" xattr).
Thanks,
Ilya

While having context information attached to each dout is nice, it
certainly comes at a price of a lot of churn and automated backport
disruption. I wonder how much value doing this for douts as opposed
to just pr_* messages actually brings?
A regular user never sees douts as enabling them without extra care
tends to be useless -- journald can't cope with the volume and quickly
starts discarding them. From the developer side, many douts already
include at least one (hashed) pointer value which is usually sufficient
to disambiguate, even if it's more cumbersome than a grep on context
information.
Thanks,
Ilya

The fsid string is a little long:
[5ea1e13c-4034-426c-bf8f-8a3a70d9e812 4236]
Maybe we could just print part of that as:
[5ea1e13c.. 4236]
?

Yeah, certainly this will break automated backporting. But this should
be okay, I can generate the backport patches for each stable release for
this patch series, so after this it will make the automated backporting
work.
> I wonder how much value doing this for douts as opposed
> to just pr_* messages actually brings?
I think the 'dout()' was introduced by printing more context info, which
includes module/function names and line#, when the
CONFIG_CEPH_LIB_PRETTYDEBUG is enabled.
Maybe we can remove CONFIG_CEPH_LIB_PRETTYDEBUG now, since the pr_* will
print the module name and also the caller for dout() and pr_* will print
the function name mostly ?

Just in some cases the client global_id is really could help much,
especially for the issues only could be hit in productions case, which
could have hundreds of clients, and we can only enable some dout() debug
logs.

If printing it at all, I would probably print the entire UUID. But
I don't have a strong opinion here.

dout() is just a wrapper around pr_debug(). It doesn't have anything
to do with CONFIG_CEPH_LIB_PRETTYDEBUG per se which adds file names and
line numbers. IIRC dout() by itself just adds a space at the front to
make debugging spew stand out.

To the best of my knowledge, CONFIG_CEPH_LIB_PRETTYDEBUG has always
been disabled by default and it's not enabled by any distribution in
their kernels. I don't think anyone out there would miss it, but then
it's not hurting either -- it's less than 20 lines of code with all
ifdef-ery included.
