[PATCH v2 0/9] Some minor fixes/additions for nvme-cli

[mwilck at suse.com]

From: Martin Wilck <mwilck at suse.com>

This series collects patches from my former submission "RFC: add "nvme
monitor" subcommand" which aren't directly related to the monitor
functionality, but required to make the monitor in its current form
compile. A v3 of the monitor code is about to follow.

The main part is the "generic logging functionality".

Changes wrt the RFC: add "nvme monitor" subcommand series: many.

 - rebased to current upstream code base e9d43dd ("[nvme-cli] Fix Max/Min 
   User data erase counts displayed in 0xC2 Log Page"))
 - renamed log() to msg() in order to prevent name clash with <math.h>
 - put logging and cleanup files in "util/" subdirectory
 - converted the bulk of the logging code from a macro into a function
   (Hannes)
 - added functionality to optionally log the PID (default off).
 - added Hannes' patch he recently submitted via github
   (https://github.com/linux-nvme/nvme-cli/pull/942), with two minor
   fixes on top, rationale in the commit messages
 - various additional fixes for memory handling

Both cleanup and logging functions / macros could be used in more
places with positive effects, but my focus is currently on preparing
the monitor functionality.

Changes v1 -> v2:

 - rebased on current upstream
 - squashed previous patches 1 and 2 into one, and simplified the logic
   (Sagi) - if the kernel has no "kato" attribute, we now simply assume
   that existing discovery controllers we encounter are persistent.
 - added Reviewed-by: trailers where appropriate

Hannes Reinecke / Martin Wilck (1):
  nvme-discover: lookup existing persistent controllers

Martin Wilck (8):
  do_discover: free cfg.device when resetting it
  nvme-connect-all(1): fix documentation for --quiet/-S
  nvme: add some simplifying macros for __attribute__((cleanup()))
  nvme-cli: add generic logging functionality
  nvme: convert some function arguments from "char *" to "const char *"
  fabrics: use "const char *" in struct config
  fabrics: fix some memory leaks
  fabrics: fix invalid memory access in discover_from_conf_file()
