notified the epoll everywhere

Bananymous 804cbeb1a7 Kernel: Increment kmalloc storage size to 64 MiB 
I really don't want to do this, but rewriting kmalloc to be dynamic
would require me to rewrite 32 bit paging and I really don't want to.

Bananymous de7c3d3d29 Kernel: Don't try to create . in USTAR

Bananymous 72f85dce2b Kernel: Make userspace stack on-demand allocated 
Also bump the hardlimit of stack size from 512 KiB->32 MiB. This still
feels quite low but is much better than before :D
 2025-08-07 16:43:05 +03:00
Bananymous f5bbcc017c Kernel: Only send one smp message when reserving a range 
This was causing some kernel panic because processors ran out of smp
message storage when reserving large areas.

Also most of the time there is no need to actually send the SMP message.
If process is mapping something to just its own address space, there is
no need for a TLB shootdown. Maybe this should be only limited to kernel
memory and threads across the same process. I'm not sure what the best
approach here and it is better to send too many invalidations that too
few!
