Subject: [PATCH v6 2/4] mm: move is_kernel_rodata() to asm-generic/sections.h
Date: Sun, 30 Sep 2018 22:26:13 +0200 [thread overview]
Message-ID: <20180930202615.12951-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20180930202615.12951-1-brgl@bgdev.pl>
Export this routine so that we can use it later in devm_kstrdup_const()
and devm_kfree().
