Subject: [PATCH 09/11] builtin rebase: start a new rebase only if none is in progress
Date: Wed,  8 Aug 2018 19:33:28 +0545	[thread overview]
Message-ID: <20180808134830.19949-10-predatoramigo@gmail.com> (raw)
In-Reply-To: <20180808134830.19949-1-predatoramigo@gmail.com>

To run a new rebase, there needs to be a check to assure that no other
rebase is in progress. New rebase operation cannot start until an
ongoing rebase operation completes or is terminated.
