From 6184fc0b8dd76c6aedc7a26e93254993e14e52de Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 24 Jun 2015 18:07:02 +0200 Subject: quota: Propagate error from ->acquire_dquot() Currently when some error happened in ->acquire_dquot(), dqget() just returned NULL. That was indistinguishable from a case when e.g. someone run quotaoff and so was generally silently ignored. However ->acquire_dquot() can fail because of ENOSPC or EIO in which case user should better know. So propagate error up from ->acquire_dquot properly.
