| Subject: [PATCH 83/85] ext4: fix incorrect block reservation on quota transfer. |
| |
| (cherry picked from commit 194074acacebc169ded90a4657193f5180015051) |
| |
| Inside ->setattr() call both ATTR_UID and ATTR_GID may be valid |
| This means that we may end-up with transferring all quotas. Add |
| we have to reserve QUOTA_DEL_BLOCKS for all quotas, as we do in |
| case of QUOTA_INIT_BLOCKS. |
