Thanks.
Greg, can you please interpret this? What does this BUG:
const unsigned char * sysfs_get_name(struct sysfs_dirent *sd) { struct attribute * attr; struct bin_attribute * bin_attr; struct relay_attribute * rel_attr; struct sysfs_symlink * sl;
if (!sd || !sd->s_element) BUG();
tell us?
I assume the bug was introduced by one of the device mapper patches:
device-mapper-snapshot-fix-origin_write-pending_exception-submission.patch device-mapper-snapshot-replace-sibling-list.patch device-mapper-snapshot-fix-invalidation.patch drivers-md-dm-raid1c-fix-inconsistent-mirroring-after-interrupted.patch dm-remove-sector_format.patch dm-make-sure-queue_flag_cluster-is-set-properly.patch md-make-sure-queue_flag_cluster-is-set-properly-for-md.patch
