complete.
ino
i-node number of the mapped file
phys_segments
number of segments in this bio after physical address
coalescing is performed.
vcnt
bio vector count which represents number of array element
(page, offset, length) which makes up this I/O request
opf
operations and flags
size
total size in bytes
rw
binary trace for read/write request
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
idx
offset into the bio vector array
devname
block device name
name
name of the probe point
bytes_done
number of bytes transferred
hw_segments
number of segments after physical and DMA remapping
hardware coalescing is performed
error
0 on success
sector
