X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a0e13dfdc391dfb2a9b165e2475fb1796c9be98d;p=users%2Fjedix%2Flinux-maple.git

devlink: health: combine loops in dump

Walk devlink instances only once. Dump the instance reporters
and port reporters before moving to the next instance.
User space should not depend on ordering of messages.

This will make improving stability of the walk easier.
