Subject: [PATCH v2 0/9] RFC: [for 5.0]: HMP monitor handlers cleanups
Date: Fri, 22 Nov 2019 18:47:58 +0200	[thread overview]
Message-ID: <20191122164807.27938-1-mlevitsk@redhat.com> (raw)

This patch series is bunch of cleanups
to the hmp monitor code.

This series only touched blockdev related hmp handlers.

No functional changes expected other that
light error message changes by the last patch.

This was inspired by this bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1719169

Basically some users still parse hmp error messages,
and they would like to have them prefixed with 'Error:'

In commit 66363e9a43f649360a3f74d2805c9f864da027eb we added
the hmp_handle_error which does exactl that but some hmp handlers
don't use it.

In this patch series, I moved all the block related hmp handlers
into blockdev-hmp-cmds.c, and then made them use this function
to report the errors.

I hope I didn't change too much code, I just felt that if
I touch this code, I can also make it easier to find these
handlers, that were scattered over 3 different files.

Changes from V1:
   * move the handlers to block/monitor/block-hmp-cmds.c
   * tiny cleanup for the commit messages

Best regards,
	Maxim Levitsky
