Jan Kara 8dce779193 ext4: Detect already used quota file early ... [ Upstream commit e0770e91424f694b461141cbc99adf6b23006b60 ] When we try to use file already used as a quota file again (for the same or different quota type), strange things can happen. At the very least lockdep annotations may be wrong but also inode flags may be wrongly set / reset. When the file is used for two quota types at once we can even corrupt the file and likely crash the kernel. Catch all these cases by checking whether passed file is already used as quota file and bail early in that case. This fixes occasional generic/219 failure due to lockdep complaint.
