- ext3-remove-ifdef-config_ext3_index.patch removed from -mm tree

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

 



The patch titled
     ext3: remove #ifdef CONFIG_EXT3_INDEX
has been removed from the -mm tree.  Its filename was
     ext3-remove-ifdef-config_ext3_index.patch

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

------------------------------------------------------
Subject: ext3: remove #ifdef CONFIG_EXT3_INDEX
From: Eric Sandeen <sandeen@xxxxxxxxxx>

CONFIG_EXT3_INDEX is not an exposed config option in the kernel, and it is
unconditionally defined in ext3_fs.h.  tune2fs is already able to turn off
dir indexing, so at this point it's just cluttering up the code.  Remove
it.
