Block allocation
hello everybody,
I want to allocate few blocks from a blockgroup in ext2 within a range of offset specified by user. Is it possible of doing so if yes then can someone please explain.As i know balloc.c and ialloc.c are responsible for it and they work on entire file system can i somehow manipulate it for ceratin ranges.
For Ex
let say i provide a range 100 - 3000. Can i allocate few blocks within this range .
Thanking you

While the filesystem mounted (and accessed through the kernel) or unmounted (and accessed via libext2fs)? Anything is possible. if you are willing to write some code....
Why do you need to do this, and is this for some class or problem set?

thank you for replying .
well iam working on a project where i need to allocate few blockgroups for manipulation of data.
yeah i can write the code but i was actually thinking that could i somehow manipulate the code at top level of allocation , so that not much changes

yeah i can write the code but i was actually thinking that could i somehow manipulate the code at top level of allocation , so that not much changes are made to the good old existing code and work is done.
if you can please provide me with some help
thank you
