fs: dont do memcopy with overlapping memory ranges #198

Closed yhr closed 2 years ago

yhr commented 2 years ago

When preparing buffered writes for the next io, we copy data within the buffer and that may lead to overlapping memory ranges that is dissallowed by memcopy. Use memmove instead to fix this.
