SYNOPSIS
ioblock.end
VALUES
None
DESCRIPTION
name - name of the probe point 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 error - 0 on success 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. hw_segments - number of
segments after physical and DMA remapping hardware coalescing is
performed size - total size in bytes
