VOP_STRATEGY — read or write a file system buffer
#include <sys/param.h> #include <sys/vnode.h> int VOP_STRATEGY(struct vnode *vp, struct buf *bp);
The arguments are: vp The vnode that the buffer is for. bp 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.
