[LUAU] controller amount of data to flush from buffer cache

[Jimen Ching]

Hi all,

I have a kernel related question, which I want to exhaust all other arenas
before bothering the linux kernel mailing list.

The problem is, I'm writing large amounts of data to disk.  I.e. 4megs per
write() call and gigabytes of data.  The buffer cache is intercepting
these write() calls and flushes what seems to be 32k at a time.  I want
the buffer cache to flush at least 512k at a time.  Can this be controlled
from userland in 2.4?  If it can be done in 2.6, I would like to hear it
too.

Thanks in advance.
