We need to initialize the stdio redirects before they're used.

Add a flush op, to return the exit code via close().
Also update bcachefs usage to use this to return fsck exit codes.

the next few patches.

bcachefs: thread_with_file: fix various printf problems2024-03-14T01:22:10ZDarrick J. Wong2024-02-07T19:39:03Zurn:sha1:1cbae651e5c875f4d128211b3c732ee545f45424
Experimentally fix some problems with stdio_redirect_vprintf by creating
a MOO variant with which we can experiment. We can't do a GFP_KERNEL
allocation while holding the spinlock, and I don't like how the printf
function can silently truncate the output if memory allocation fails.

Create a new run_thread_with_stdout function that opens a file in
O_RDONLY mode so that the kernel can write things to userspace but
userspace cannot write to the kernel. This will be used to convey xfs
health event information to userspace.
