Also I've already given up, I feel the need to still answer at least that: After thinking a bit about the problem I had the idea that a FS-wide switch like the one I've implemented might be a very easy way to implement something which would be enough for my needs (and maybe the needs of someone else). Then I've looked at the FAT sources because I know a bit about FAT and it seemed to me like one of the more easier places to test my aproach. And it was. After around 3 hours I had something working which wiped files from FAT by overwriting them. Then I've spend 1-2 hours to add the syscall and add -s to rm and some days later and another 3 hours I had the same for working for ext4. That already almost covers all my needs, maybe I'll spend another few hours to look if it's that easy with BTRFS too. So, because I've already had filed bugs #92261 and #92271 in the kernels bugzilla, I've posted that stuff. Nothing more nothing less. > You have the attention to move this forward, so please take > advantage of this. Sorry, but I'm unable to spend all the necessary time to make this perfect in regard to whatever maintainers requesting. I'll posted these patches more as some thought-provoking impulse (proof of concept), and I failed obviously badly in marking them as such. I'm sorry if I've wasted your time.
