Re: [PATCH][ATM]: [clip] fix race between modifying entry->vccs and clip_start_xmit()

chas williams [off-list ref] :
[unlink_clip_vcc() locking change]

Afaik unlink_clip_vcc() can be called from a clip_push() issued in IRQ
context through vcc->push() in a device driver as well as from user-space
through vcc_ioctl()/ATMARP_SETENTRY. If the lock is taken by user-space
first, what avoids that unlink_clip_vcc(IRQ) deadlocks on it ?

No comment for the clip_start_xmit() part btw.
