recalc_sigpending in usb.c

recalc_sigpending in usb.c

Post by Jacek Pliszk » Sat, 14 Sep 2002 11:30:06


I am trying to compile  2.5.34. But during make modules_install

depmod: *** Unresolved symbols in
depmod:         show_trace
depmod:         recalc_sigpending

When I comment out show_trace and add

to kernel/ksyms.c

make modules_install works but then

modprobe usb-storage gives:

/lib/modules/2.5.34/kernel/drivers/usb/storage/usb-storage.o: unresolved
symbol recalc_sigpending
/lib/modules/2.5.34/kernel/drivers/usb/storage/usb-storage.o: insmod
/lib/modules/2.5.34/kernel/drivers/usb/storage/usb-storage.o failed
/lib/modules/2.5.34/kernel/drivers/usb/storage/usb-storage.o: insmod
usb-storage failed

If I comment out recalc_sigpending instead - the drive does not
work at all. Hangs during eject.

Drive worked, though slowly in 2.4.18-10 (Red Hat 7.3)

I am sorry I am not subscribed so please, CC the answer to me.

Thanks for any help you could provide,

1. recalc_sigpending() / recalc_sigpending_tsk() ?

I'm looking at merging the changes made to JFFS2 in 2.5, with the intention
of again having a single codebase that compiles in both 2.5 and 2.4.

I'm a little confused by the changes to recalc_sigpending().

It seems that the name of the function was changed to recalc_sigpending_tsk()
and a new function called recalc_sigpending() was added.

Was there a reason for doing this, rather than just introducing the new
function with a different name, such as recalc_sigpending_cur()? It breaks
2.4 source compatibility in a way that seems entirely gratuitous.

Before I have to go and do something evil in my compatmac.h to work round
this, is there any chance of putting the original recalc_sigpending() back?

Linus, would you accept such a patch?


#include <linux/sched.h>
/* Grrr. Gratuitous breakage */
#define recalc_sigpending() recalc_sigpending(current)
/* Unfortunately this one can't work, because of the above
#define recalc_sigpending_tsk(t) recalc_sigpending(t)
