Can a bio have more sectors than a file system block size

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

In the make_request callback function is it possible for a bio to have
bio_sectors() count more than the number of sectors in a file system
block ?

eg : If the disk sector size is 512 bytes and file system block size
is 4096 bytes, I have only noticed bio_sectors() to be 8. Never seen
anything more or less than 8.

Regards.
