But m_o_lock_completed only means that dirty pages have been sent to the translator, and this one still needs to write them to the backing storage + <slpz> guillem: there's no problem if sync() returns before actually writting the changes to disk, but this also happens when shutting down the translator + <slpz> guillem: in theory, locking mechanisms in libpager should prevent this from happening by keeping track of write operations, but this seems to fail in some situations |
