The patch titled
Subject: nilfs2: replace nilfs_warning() with nilfs_msg()
has been removed from the -mm tree. Its filename was
nilfs2-replace-nilfs_warning-with-nilfs_msg.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Ryusuke Konishi <konishi.ryusuke@xxxxxxxxxxxxx>
Subject: nilfs2: replace nilfs_warning() with nilfs_msg()
Use nilfs_msg() to output warning messages and get rid of nilfs_warning()
function. This also removes function names from the messages unless we
embed them explicitly in format strings. Instead, some messages are
revised to clarify the context.
[arnd@xxxxxxxx: avoid warning about unused variables]
