Subject: [PATCH v5 2/3] xl: Make set_memory_target return an error code on failure
Date: Thu, 24 Mar 2016 17:17:23 +0000 [thread overview]
Message-ID: <1458839844-26238-3-git-send-email-george.dunlap@citrix.com> (raw)
In-Reply-To: <1458839844-26238-1-git-send-email-george.dunlap@citrix.com>
From: George Dunlap <george.dunlap@eu.citrix.com>
Also move the rc -> shell code translation into set_memory_max() to
make the two functions consistent with each other, and with other
similar examples in xl_cmdimpl.c
Change a 'long long' to "int64_t" while we're at it.
Signed-off-by: George Dunlap <george.dunlap@eu.citrix.com>
Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>

v4:
- Move rc -> shell return code translation into set_memory_{max,target}
- Use EXIT_{SUCCESS,FAILURE} rather than magic constants
- Note incidental type change in changelog
