https://bugzilla.kernel.org/show_bug.cgi?id=89131 --- Comment #11 from Theodore Tso <tytso@xxxxxxx> --- Created attachment 163831 --> https://bugzilla.kernel.org/attachment.cgi?id=163831&action=edit debugging patch (should apply for 3.17 and 3.18) This BUG_ON is happening from the mm part of the direct_io code, which is supposed to be file system independent, and so I don't know that half of the DIO code as well. Can you try applying the attached patch to see if it gets us any useful information when the bug triggers? Also, at this point it would be *really* useful if we could get a reproduction case that doesn't require using rtorrent -- i.e., something that uses just dd, or maybe a simple C program. Would it be possible to run the a tty-mode torrent on a serial console under strace, or some such, so we can get figure out what the system calls were that apparently triggered the BUG_ON? -- 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
