| |
Short question: Is it possible to locate the struct file * associated with a bio? If so, how?
Longer version: I am working on a project that requires measuring the popularity of each file in a filesystem. I have made several attempts to locate all the file reads by grepping for ->readpage() and ->readpages() calls, but I am still missing several file reads. I have not yet looked for file writes.
I *have* been able to catch every bio access, which leads to my question. Is it possible to locate the struct file * associated with a bio? If so, how? Efficiency is not my primary issue right now. I'm mainly concerned with it "just working."
Thanks in advance!
