Conrad Meyer 20172854ab Add sbuf streaming mode to pseudofs(9), use in linprocfs(5) ... Add a pseudofs node flag 'PFS_AUTODRAIN', which automatically emits sbuf contents to the caller when the sbuf buffer fills. This is only permissible if the corresponding PFS node fill function can sleep whenever it appends to the sbuf. linprocfs' /proc/self/maps node happens to meet this requirement. Streaming out the file as it is composed avoids truncating the output and also avoids preallocating a very large buffer.
