Subject: ext4: ext4_mkdir should dirty dir_block with newly created directory inode
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9287c1f2d329f4d78a3bbc9cf0db0ebae6f146a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ext4: ext4_mkdir should dirty dir_block with newly created directory inode

ext4_mkdir calls ext4_handle_dirty_metadata with dir_block and the inode "dir".
Unfortunately, dir_block belongs to the newly created directory (which is
"inode"), not the parent directory (which is "dir").  Fix the incorrect
association.
