Actually argh, too many bugs. ;) I was thinking of https://bugzilla.redhat.com/show_bug.cgi?id=857618 which has been reported a few times, and hits a BUG() in 1965 ext4_ext_put_in_cache(struct inode *inode, ext4_lblk_t block, 1966 __u32 len, ext4_fsblk_t start) 1967 { 1968 struct ext4_ext_cache *cex; 1969 BUG_ON(len == 0); but that's not what this reporter sees, sorry for the noise. (Lukas pointed at upstream commit 31d4f3a2f3c73f279ff96a7135d7202ef6833f12 to avoid the BUG_ON but we still don't know the root cause I think). Anyway, now I'm OT for this thread. -Eric -- 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
