Quite frankly, using a 3.10 kernel borders on malpractice, since it has so many unpatched security holes it isn't funny. If you are talking about a RHEL kernel, it has diverged significantly from mainline and whether or not it is a security disaster is between you and your Red Hat support contract. :-) My comments apply mainly to the the upstream development kernel, but to answer your questions: No, in 3.10, generic_writepages() does not call ext4_da_writepages(). And ext4_da_writepages roughly corresponds to what ext4_writepages() in non-obsolete kernels. A huge number of things have changed between 3.10 and more modern kernels, including many performance enhancements. So some of the details have changed. -- You are receiving this mail because: You are watching the assignee of the bug.
