Today's next fails to build on a s390 box with
CC kernel/workqueue.o
kernel/workqueue.c: In function 'init_workqueues':
kernel/workqueue.c:3525: error: negative width in bit-field '<anonymous>'
make[1]: *** [kernel/workqueue.o] Error 1
Yesterday's next was good.
The following patches added/changed the BUILD_BUG_ON() statement.
bdbc5dd7de5d07d6c9d3536e598956165a031d4c
workqueue: prepare for WQ_UNBOUND implementation
7a22ad757ec75186ad43a5b4670fa7423ee8f480
workqueue: carry cpu number in work data once execution starts
I have gcc version 4.3.2 installed on the system.
Thanks

Hmmm... that's surprising. Can you please attach the .config? Thanks. -- tejun ^ permalink raw reply [flat|nested] 8+ messages in thread

Can you please attach the .config? The BUILD_BUG_ON line gets expanded to: ((void)(sizeof(struct { int:-!!(WORK_CPU_LAST << WORK_STRUCT_FLAG_BITS >= 0x0UL); }))); WORK_CPU_LAST is: enum { .. WORK_CPU_NONE = 32 + 1, WORK_CPU_LAST = WORK_CPU_NONE, .. }; WORK_STRUCT_FLAG_BITS is: WORK_STRUCT_COLOR_SHIFT = 2, WORK_STRUCT_COLOR_BITS = 4, WORK_STRUCT_FLAG_BITS = WORK_STRUCT_COLOR_SHIFT + WORK_STRUCT_COLOR_BITS, which boils it down to ((void)(sizeof(struct { int:-!!(33 << 6 >= 0x0UL); }))); gcc doesn't like this construct. -- blue skies, Martin.

This is added by commit 7a22ad75 (workqueue: carry cpu number in work data once execution starts) to reliably determine the work was last on even if the workqueue itself was destroyed inbetween. Whether data points to a cwq or contains a cpu number was distinguished by comparing the value against PAGE_OFFSET. The assumption was that a cpu number should be below PAGE_OFFSET while a pointer to cwq should be above it. However, on architectures which use separate address spaces for user and kernel spaces, this doesn't hold as PAGE_OFFSET is zero. Fix it by using an explicit flag, WORK_STRUCT_CWQ, to mark what the data field contains. If the flag is set, it's pointing to a cwq; otherwise, it contains a cpu number. Reported on s390 and microblaze during linux-next testing.
