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. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
