Also I've already given up, I feel the need to still answer at least th= at: After thinking a bit about the problem I had the idea that a FS-wide=20 switch like the one I've implemented might be a very easy way to=20 implement something which would be enough for my needs (and maybe the=20 needs of someone else). Then I've looked at the FAT sources because I=20 know a bit about FAT and it seemed to me like one of the more easier=20 places to test my aproach. And it was. After around 3 hours I had something working which wiped=20 files from FAT by overwriting them. Then I've spend 1-2 hours to add th= e=20 syscall and add -s to rm and some days later and another 3 hours I had=20 the same for working for ext4. That already almost covers all my needs,= =20 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 kernel= s=20 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=20 perfect in regard to whatever maintainers requesting. I'll posted these= =20 patches more as some thought-provoking impulse (proof of concept), and = I=20 failed obviously badly in marking them as such. I'm sorry if I've wasted your time.
