Analyze and fix the following issue in the Linux kernel code: fs/pipe: Fix lockdep false-positive in watchqueue pipe_write()
Problem Details: When you try to splice between a normal pipe and a notification pipe, get_pipe_info(..., true) fails, so splice() falls back to treating the notification pipe like a normal pipe - so we end up in iter_file_splice_write(), which first locks the input pipe, then calls vfs_iter_write(), which locks the ou...
