https://bugzilla.kernel.org/show_bug.cgi?id=124651 --- Comment #1 from Theodore Tso <tytso@xxxxxxx> --- This is a Red Hat kernel, so ideally you should be reporting this to Red Hat. Because it's a Red Hat kernel, I can't easily determine what's on line 2263 of fs/ext4/inode.c: [55359.508185] kernel BUG at fs/ext4/inode.c:2263! If you have access to Red Hat sources, can you give me an indication of what's on that line? One of the reasons why I ask is if I look at the upstream sources, the only BUG_ON in mpage_prepare_extent_to_map is this one: wait_on_page_writeback(page); BUG_ON(PageWriteback(page)); And that's clearly a bug outside of ext4, because we've locked the page, so once the page writeback flag is cleared, it shouldn't be set again. So either someone woke up the page without clearing the PageWriteback flag, or some other racing process attempted to set the PageWriteback flag without holding the page lock. But this is assuming I'm looking at the correct BUG_ON --- and since this is a Red Hat kernel, I can't be sure. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
