From 12755627bdcddcdb30a1bfb9a09395a52b1d6838 Mon Sep 17 00:00:00 2001 From: Dmitry Monakhov Date: Thu, 8 Apr 2010 22:04:20 +0400 Subject: quota: unify quota init condition in setattr Quota must being initialized if size or uid/git changes requested. But initialization performed in two different places: in case of i_size file system is responsible for dquot init , but in case of uid/gid init will be called internally in dquot_transfer(). This ambiguity makes code harder to understand. Let's move this logic to one common helper function.
