after a crash and a potential BUG_ON crash if a file has the data journalling flag enabled while it has dirty delayed allocation blocks that haven't been written yet. Also fix a potential crash in the new project quota code and a maliciously corrupted file system. In addition, fix some DAX-specific bugs, including when there is a transient ENOSPC situation and races between writes via direct I/O and an mmap'ed segment that could lead to lost I/O. Finally the usual set of miscellaneous cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAABCAAGBQJXQ40fAAoJEPL5WVaVDYGjnwMH+wXHASgPfzZgtRInsTG8W/2L jsmAcMlyMAYIATWMppNtPIq0td49z1dYO0YkKhtPVMwfzu230IFWhGWp93WqP9ve XYHMmaBorFlMAzWgMKn1K0ExWZlV+ammmcTKgU0kU4qyZp0G/NnMtlXIkSNv2amI 9Mn6R+v97c20gn8e9HWP/IVWkgPr+WBtEXaSGjC7dL6yI8hL+rJMqN82D76oU5ea vtwzrna/ISijy+etYmQzqHNYNaBKf40+B5HxQZw/Ta3FSHofBwXAyLaeEAr260Mf V3Eg2NDcKQxiZ3adBzIUvrRnrJV381OmHoguo8Frs8YHTTRiZ0T/s7FGr2Q0NYE= =7yIM -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 updates from Ted Ts'o: "Fix a number of bugs, most notably a potential stale data exposure after a crash and a potential BUG_ON crash if a file has the data journalling flag enabled while it has dirty delayed allocation blocks that haven't been written yet.
