unprivileged mount problems: device permissions ignored, mount sharing

Hello I tried the unprivileged mount v5 patches with 2.6.21.1. I made some experiments with normal filesystems (ext3, xfs, iso9660). I removed the FS_SAFE checks for that. Mounting and umounting as unprivileged user (user1) works, e.g. (/mnt/user1 is a mount owned by user1) [EMAIL PROTECTED] ~]$

Re: [PATCH]sched: Isochronous class v2 for unprivileged soft rt scheduling

Hi I dislike the behavior of the SCHED_ISO patch that iso tasks are degraded to SCHED_NORMAL if they exceed the limit. IMHO it's better to throttle them at the iso_cpu limit. I have modified Con's iso2 patch to do this. If iso_cpu > 50 iso tasks only get stalled for 1 tick (1ms on x86). Fortunat
