The following patch fixes that problem on > my system. I just looked at the source; I forgot `make checkstack' existed. On this system: 0xc0263e0f pkt_open [vmlinux]: 556 which is nearly as bad. (As an aside, I'm surprised I didn't oops when packet-writing as well: 0xc021270d udf_process_sequence [vmlinux]: 692 0xc020f43d udf_add_entry [vmlinux]: 628 owch. I guess that's called via a shorter call chain...) I'll try the patch after this series of backups is done :) -- `The rest is a tale of post and counter-post.' --- Ian Rawlings describes USENET -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
