Hi all,

After merging the block tree, today's linux-next build (x86_64
allnoconfig) failed like this:

fs/libfs.c: In function 'generic_file_fsync':
fs/libfs.c:1116:9: error: too few arguments to function 'blkdev_issue_flush'
 1116 |  return blkdev_issue_flush(inode->i_sb->s_bdev, GFP_KERNEL);
      |         ^~~~~~~~~~~~~~~~~~
In file included from fs/libfs.c:7:
include/linux/blkdev.h:1875:19: note: declared here
 1875 | static inline int blkdev_issue_flush(struct block_device *bdev, gfp_t gfp_mask,
      |                   ^~~~~~~~~~~~~~~~~~

Caused by commit

  c64644ce363b ("block: remove the error_sector argument to blkdev_issue_flush")

I have applied the following patch.
