Hi all, Today's linux-next merge of the fs-next tree got a conflict in: mm/filemap.c between commit: 0ff9a4200192d ("mm: limit pagecache folio refcount when splicing into pipes") from the mm-fixes tree and commit: 028bbac710376 ("fs: annotate lockless file position updates in sendfile") from the fs-next tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. diff --cc mm/filemap.c index d96ea2c9db285,c9bc0fdf15ad4..0000000000000 --- a/mm/filemap.c +++ b/mm/filemap.c @@@ -3183,8 -3175,9 +3183,9 @@@ ssize_t filemap_splice_read(struct fil len -= n; total_spliced += n; *ppos += n; - in->f_ra.prev_pos = *ppos; + /* readahead hint, racy updates are benign */ + data_race(in->f_ra.prev_pos = *ppos); - if (pipe_is_full(pipe)) + if (pipe_is_full(pipe) || *ppos < folio_next_pos(folio)) goto out; }
