All,
I'm rather at a loss to understand what .truncate is supposed to do when
it _extends_ a file (2.5.68+ kernel). Looking through the examples in
the tree, I don't see where they deal with that case. Could someone
give me a clue as to how .truncate is supposed to...tell the kernel what
blocks it is to use when it goes to read from the extended portion of
the file?
So far, I have googled, grep'ed, looked at lwn.net, started in on
linux.bkbits.net, emailed linux-fsdevel and kernel-newbies... and I'm
still not getting anywhere. Even a basic explanation of how filesystems
deal/interact with buffer heads and inodes would probably help at this
point.
Any clues or pointers or _anything_ would be very much appreciated. :/
