[Chaitanya Kulkarni]

Just like we have open coded NVME_FEAT_HOST_ID handling, open code one

When I pulled the changes today it didn't show this patch-series,
git HEAD is pointing to

"nvmet: use snprintf() with PAGE_SIZE in configfs" :-

nvme (nvme-5.18) # gitpulltheirs
warning: Pulling without specifying how to reconcile divergent branches is
discouraged. You can squelch this message by running one of the following
commands sometime before your next pull:

   git config pull.rebase false  # merge (the default strategy)
   git config pull.rebase true   # rebase
   git config pull.ff only       # fast-forward only

You can replace "git config" with "git config --global" to set a default
preference for all repositories. You can also pass --rebase, --no-rebase,
or --ff-only on the command line to override the configured default per
invocation.

Already up to date.

     nvmet: use snprintf() with PAGE_SIZE in configfs

     Instead of using sprintf, use snprintf with buffer size limited to
     PAGE_SIZE just like what we have for the rest of the file.

Please revert this series I've made a mistake when sending this series
that is breaking the build, will send out a right one later.

Sorry for the inconvenience.

[Christoph Hellwig]

I had to drop it again as it caused compile failures.  These helpers
are also used in discovery.c.
