I have a question regarding how the Linux kernel handles slack space.
I know that the ext3 filesystems typically use 1,2 or 4 KB blocks and
if a file is not an even multiple of the block size then the last
allocated block will not be completely filled, the remaining space is
wasted as slack space.
What I need is the code in the kernel that does that. I have been
looking at http://lxr.linux.no/source/fs/ext3/inode.c but I could not
find the specific code for partially filling the last block and
placing an EOF at the end, leaving the rest to slack space.
Please forward the answer to [email protected] as soon as possible.
Thank you very much.
