Hi,
# ulimit -f `echo 2^22-1|bc`;ulimit -f
4194303
# ulimit -f `echo 2^22|bc`;ulimit -f
unlimited
# uname -r
2.6.11-1.1290_FC4
I need to limit users to 5GB per file instead of 4GB. Do I need any
kernel patches or can it somehow be done in user space?
Thanks
Igor

The syscall (and also glibc glue) for this only support 32-bit values.
It's probably not hard to make a 64-bit version of these system calls
(I'm not sure about the glibc changes though).
