Date: Tue, 10 Dec 2013 11:13:58 +0100 From: Jan Kara <jack@...e.cz> To: Ted Tso <tytso@....edu> Cc: Akira Fujita <a-fujita@...jp.nec.com>, linux-ext4@...r.kernel.org, Jan Kara <jack@...e.cz> Subject: [PATCH 1/3] 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.
