X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d7433142b63d727b5a217c37b1a1468b116a9771;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ext3: Always set dx_node's fake_dirent explicitly. (crossport of 1f7bebb9e911d870fa8f997ddff838e82b5715ea by Andreas Schlick ) When ext3_dx_add_entry() has to split an index node, it has to ensure that name_len of dx_node's fake_dirent is also zero, because otherwise e2fsck won't recognise it as an intermediate htree node and consider the htree to be corrupted.
