OK, fakeroot does PRELOADing so your assumption makes sense. How can I trigger fakeroot calls? Here I have... /usr/bin/faked-sysv /usr/bin/faked-tcp I think that is the main commit but I am not sure if I can revert the idr_preload part, otherwise it gets complicated: commit e2802c2defba1e5c88d7d168eb5c66813c86f249 "idr: implement idr_preload[_end]() and idr_alloc()" $ grep idr ../Linux-Next-v20130206-VS-v20130207.diff | grep ^'++Applying:' ++Applying: block: fix ext_devt_idr handling ++Applying: idr: fix a subtle bug in idr_get_next() ++Applying: nfsd: idr_destroy() no longer needs idr_remove_all() ++Applying: idr: cosmetic updates to struct / initializer definitions ++Applying: idr: relocate idr_for_each_entry() and reorganize id[r|a]_get_new() ++Applying: idr: remove _idr_rc_to_errno() hack ++Applying: idr: refactor idr_get_new_above() ++Applying: idr: implement idr_preload[_end]() and idr_alloc() ++Applying: block: convert to idr_alloc() ++Applying: block/loop: convert to idr_alloc() ++Applying: atm/nicstar: convert to idr_alloc() ++Applying: drbd: convert to idr_alloc() ++Applying: dca: convert to idr_alloc() ++Applying: dmaengine: convert to idr_alloc() ++Applying: firewire: convert to idr_alloc() ++Applying: gpio: convert to idr_alloc() ++Applying: drm: convert to idr_alloc() ++Applying: drm/exynos: convert to idr_alloc() ++Applying: drm/i915: convert to idr_alloc() ++Applying: drm/sis: convert to idr_alloc() ++Applying: drm/via: convert to idr_alloc() ++Applying: drm/vmwgfx: convert to idr_alloc() ++Applying: i2c: convert to idr_alloc() ++Applying: IB/core: convert to idr_alloc() ++Applying: IB/amso1100: convert to idr_alloc() ++Applying: IB/cxgb3: convert to idr_alloc() ++Applying: IB/cxgb4: convert to idr_alloc() ++Applying: IB/ehca: convert to idr_alloc() ++Applying: IB/ipath: convert to idr_alloc() ++Applying: IB/mlx4: convert to idr_alloc() ++Applying: IB/ocrdma: convert to idr_alloc() ++Applying: IB/qib: convert to idr_alloc() ++Applying: dm: convert to idr_alloc() ++Applying: memstick: convert to idr_alloc() ++Applying: mfd: convert to idr_alloc() ++Applying: misc/c2port: convert to idr_alloc() ++Applying: misc/tifm_core: convert to idr_alloc() ++Applying: mmc: convert to idr_alloc() ++Applying: mtd: convert to idr_alloc() ++Applying: macvtap: convert to idr_alloc() ++Applying: ppp: convert to idr_alloc() ++Applying: power: convert to idr_alloc() ++Applying: pps: convert to idr_alloc() ++Applying: remoteproc: convert to idr_alloc() ++Applying: rpmsg: convert to idr_alloc() ++Applying: scsi/bfa: convert to idr_alloc() ++Applying: scsi: convert to idr_alloc() ++Applying: target/iscsi: convert to idr_alloc() ++Applying: scsi/lpfc: convert to idr_alloc() ++Applying: thermal: convert to idr_alloc() ++Applying: uio: convert to idr_alloc() ++Applying: vfio: convert to idr_alloc() ++Applying: dlm: convert to idr_alloc() ++Applying: inotify: convert to idr_alloc() ++Applying: ocfs2: convert to idr_alloc() ++Applying: ipc: convert to idr_alloc() ++Applying: cgroup: convert to idr_alloc() ++Applying: events: convert to idr_alloc() ++Applying: posix-timers: convert to idr_alloc() ++Applying: net/9p: convert to idr_alloc() ++Applying: mac80211: convert to idr_alloc() ++Applying: sctp: convert to idr_alloc() ++Applying: nfs4client: convert to idr_alloc() - Sedat - [1] http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git;a=commitdiff;h=e2802c2defba1e5c88d7d168eb5c66813c86f249 > Eric -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
