Hi all,
After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
mm/readahead.c: In function 'page_cache_sync_ra':
mm/readahead.c:565:8: error: 'filp' undeclared (first use in this function); did you mean 'file'?
565 | if (!filp)
| ^~~~
| file
Caused by commit
f65bd470e7ed ("mm/readahead: add page_cache_sync_ra and page_cache_async_ra")
interacting with commit
09d008e3868e ("readahead: use limited read-ahead to satisfy read")
from the block tree.
I have added the following merge fix patch.
