Date: Mon, 25 Feb 2013 20:07:42 +0400 From: Dmitry Monakhov <dmonakhov@...nvz.org> To: linux-ext4@...r.kernel.org Cc: tytso@....edu, jack@...e.cz, wenqing.lz@...bao.com, Dmitry Monakhov <dmonakhov@...nvz.org> Subject: [PATCH 4/5] ext4: remove unnecessary wait for extent conversion in ext4_fallocate() From: Jan Kara <jack@...e.cz> 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.
