SubjectRe: [PATCH] zerocopy NFS updated

Write in append mode must be atomic in the kernel. Whether a user
space write in append mode is atomic or not depends on how many
write() syscalls it takes to pass the data into the kernel. Each
write() append will be atomic but multiple writes can be
interleaved.

Up to what size? I assume I cannot assume O_APPEND atomicity for
(say) 100M writes?
