Subject: [PATCH 1/5] mm/vmalloc: remove the unnecessary type check
Date: Mon,  6 Jun 2022 16:39:05 +0800	[thread overview]
Message-ID: <20220606083909.363350-2-bhe@redhat.com> (raw)
In-Reply-To: <20220606083909.363350-1-bhe@redhat.com>

In function adjust_va_to_fit_type(), it checks all values of passed
in fit type, including NOTHING_FIT in the else branch. In fact, it's
unnecessary to check NOTHING_FIT since the check has been done before
adjust_va_to_fit_type() is called in all call sites. So clean it up.
