From de99fcce1da7933a90198b80a2e896754ea3bdc8 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 4 Mar 2013 00:43:32 -0500 Subject: [PATCH] ext4: remove unnecessary wait for extent conversion in ext4_fallocate() Now that we don't merge uninitialized extents anymore, ext4_fallocate() is free to operate on the inode while there are still some extent conversions pending - it won't disturb them in any way.
