Hi all,
After merging the folio tree, today's linux-next build (x86_64
allmodconfig) failed like this:
fs/9p/vfs_file.c: In function 'v9fs_vm_page_mkwrite':
fs/9p/vfs_file.c:557:6: error: implicit declaration of function 'wait_on_page_bit_killable'; did you mean 'wait_on_page_locked_killable'? [-Werror=implicit-function-declaration]
557 | wait_on_page_bit_killable(page, PG_writeback) < 0)
| ^~~~~~~~~~~~~~~~~~~~~~~~~
| wait_on_page_locked_killable
Caused by commit
be8f72914261 ("mm/filemap: Add folio_wait_bit()")
interacting with commit
82766b47b26c ("9p: (untested) Convert to using the netfs helper lib to do reads and caching")
from the fscache tree.
I have applied the following merge fix patch.
