FS_NOWAIT looks a bit too generic given these are filesystem feature flags.
Can we call it FS_NOWAIT_IO?

It's way to generic as it's a feature of the particular file_operations
instance.  But once we switch to using RWF_* we can just the existing
per-op feature checks for thos and the per-fs flag should just go away.

I am working on incorporating RWF_* flags. However, I am not sure how
RWF_* flags would get rid of FS_NOWAIT/FS_NOWAIT_IO. Since most of
"blocking" information is with the filesystem, it is a per-filesystem
flag to block out (EOPNOTSUPP) the filesystems which do not support it.
