From bc0ca9df3b2abb13f7da9d8d255ec60718badd84 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 6 Jan 2014 14:02:23 -0500 Subject: [PATCH] ext4: retry allocation when inline->extent conversion failed Similarly as other ->write_begin functions in ext4, also ext4_da_write_inline_data_begin() should retry allocation if the conversion failed because of ENOSPC. This avoids returning ENOSPC prematurely because of uncommitted block deletions.
