From 8bc3b1e6e8fdc1c605c06c027d999b5cca434779 Mon Sep 17 00:00:00 2001 From: David Moore Date: Mon, 8 Jun 2015 11:59:12 -0400 Subject: [PATCH] ext4: BUG_ON assertion repeated for inode1, not done for inode2 During a source code review of fs/ext4/extents.c I noted identical consecutive lines. An assertion is repeated for inode1 and never done for inode2. This is not in keeping with the rest of the code in the ext4_swap_extents function and appears to be a bug. Assert that the inode2 mutex is not locked.
