The patch titled

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Ryusuke Konishi <konishi.ryusuke@xxxxxxxxxxxxx>
Subject: nilfs2: get rid of nilfs_mdt_mark_block_dirty()
nilfs_mdt_mark_block_dirty() can be replaced with primary functions
like nilfs_mdt_get_block() and mark_buffer_dirty(), and it's used only
by nilfs_ioctl_mark_blocks_dirty().
This gets rid of the function to simplify the interface of metadata
file.
