Subject: [PATCH] ramfs breaks without CONFIG_BLOCK
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=131612dfe7923bd0ce5f82d6ed8303a7ef96e574;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] ramfs breaks without CONFIG_BLOCK

ramfs doesn't provide the .set_dirty_page a_op, and when the BLOCK layer is
not configured in, 'set_page_dirty' makes a call via a NULL pointer.
