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
The process signals the transfer is done.
