This works asynchronously.
So you should __not__ expect the same ordering in execution of bio->bi_endio ()

Subject: A doubt regarding submit_bio()
Hello all,
I am working on a operation in which I need to assure the order of
bio_end_io() functions.
Consider the scenario,
If I submit two bio requests using submit_bio() function one after
another, then is there any guarantee that the bio_end_io() for the
bios will be invoked in the same order in which I submitted the bios?
Basically I mean to say, would the generic block layer or I/O
scheduler maintain the order of bios submitted to them?
Hoping for some help.
Regards,
Gaurav.
