However we're reading/writing a single page here and page read/write shoud be atomic so we should _not_ see page with mixed data. Basically the page should be locked when we copy data from/to it, -Lukas -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
