[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch titled
     Subject: fs: don't open code lru_to_page()
has been removed from the -mm tree.  Its filename was
     fs-dont-opencode-lru_to_page.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Nikolay Borisov <nborisov@xxxxxxxx>
Subject: fs: don't open code lru_to_page()

Multiple filesystems open code lru_to_page().  Rectify this by moving the
macro from mm_inline (which is specific to lru stuff) to the more generic
mm.h header and start using the macro where appropriate.

No functional changes.
