Description: Adds rwsemaphore hydsn_cards_sem. hydsn_cards_sem guards the card_root list. It is a read/write semaphore which must be held for write when modifying the list. I've been examining the continuing additions of the big kernel lock (BKL) to the 2.5 tree. I noticed that in 2.5.3, the ISDN subsystem added the BKL to several places. In response to this, I have written several patches to attempt removal of the BKL from the ISDN subsystem. I have little knowledge of the drivers themselves, so I would like some assistance from those of you who understand them better. I probably have an over-simplified view of the code, so my patches may be too simplistic. |
