Génial !!! Amazing !!! i use :6,13s/^/# for add a # in front of lines ! Merci beaucoup
How to off this
Oh so there is a uboot configuration tailor made for qemu 64 bit??? Thank you so much
Someone send it to crowdstrike.
Crowdstrike 😂
that's exactly why I came to see this
Lol
But notice how the kernel gently discards a failing module without a total screw-up of the OS. I wonder also if some other compile-time options would've caught the null pointer dereference at compile time? -pedantic or -Wnull-dereference ?
nice video
Great
thank you so much
Thanks
thanks! exactly what i wanted
hey what if I have 2 modules and in each modules have functions which are dependent upon each other. in this case we can't load the module
Heyy can you upload the text file which has the command listed, it would be really helpful for your users.
Cool, thank you
didn't understand even a thing*
perfect
Short and sweet. Thank you.
