[PATCH v2 01/28] csky,sparc: Declare flush_dcache_folio()
From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
Date: 2021-11-08 04:12:52
Also in:
linux-fsdevel, linux-xfs, lkml
Subsystem:
c-sky architecture, sparc + ultrasparc (sparc/sparc64), the rest · Maintainers:
Guo Ren, "David S. Miller", Andreas Larsson, Linus Torvalds
These architectures do not include asm-generic/cacheflush.h so need
to declare it themselves.
Fixes: 08b0b0059bf1 ("mm: Add flush_dcache_folio()")
Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
