read or write a file system buffer
vnode *vp, struct buf
The arguments are:
- The vnode that the buffer is for.
- The buffer to be read or written.
This call either reads or writes data from a file, depending on the value of bp->b_io.bio_cmd.
The call may block.
Always zero. Errors should be signalled by setting BIO_ERROR on b_ioflags field in struct buf, and setting b_error to the appropriate errno value.
