       probe::ioblock_trace.end - Fires whenever a block I/O transfer is complete.






       name - name of the probe point q - request queue on which this bio was queued.  devname -
       block device name ino - i-node number of the mapped file bytes_done - number of bytes
       transferred sector - beginning sector for the entire bio flags - see below BIO_UPTODATE 0
       ok after I/O completion BIO_RW_BLOCK 1 RW_AHEAD set, and read/write would block BIO_EOF 2
       out-out-bounds error BIO_SEG_VALID 3 nr_hw_seg valid BIO_CLONED 4 doesn't own data
       BIO_BOUNCED 5 bio is a bounce bio BIO_USER_MAPPED 6 contains user pages BIO_EOPNOTSUPP 7
       not supported

       rw - binary trace for read/write request vcnt - bio vector count which represents number
       of array element (page, offset, length) which makes up this I/O request idx - offset into
       the bio vector array phys_segments - number of segments in this bio after physical address
       coalescing is performed.  size - total size in bytes bdev - target block device
       bdev_contains - points to the device object which contains the partition (when bio
       structure represents a partition) p_start_sect - points to the start sector of the
       partition structure of the device


       The process signals the transfer is done.
