Subject: Issue in ext4 rename
Hi all,
In ext4_rename_delete, it only logs a warning if ext4_delete_entry
fails.
IMO, it may lead to an inode with two entries (old and new), thus
filesystem will be inconsistent.
The case is described below:
ext4_rename
--> ext4_journal_start
--> ext4_add_entry (new)
--> ext4_rename_delete (old)
--> ext4_delete_entry
--> ext4_journal_get_write_access
*failed* because of -ENOMEM
--> ext4_journal_stop
Does anyone have an idea to resolve this issue?
