Subject: Make alloc_page_buffers() initialise buffer_heads using init_buffer(),
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=01ffe339e3a0ba5ecbeb2b3b5abac7b3ef90f374;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Make alloc_page_buffers() initialise buffer_heads using init_buffer(),
like other routines here, to ensure buffers are correctly initialised
with respect to b_private/b_end_io.  Fixes an odd interaction between
XFS and reiserfs.
