Hello Andrew!
I have the following problem on 2.6.15-rc5-mm1
When compiling a module using spinlocks I get the following error-message, when SMP is disabled in my Kernel-config:
In file included from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:7: include/asm/spinlock.h:21:1: warning: "__raw_spin_is_locked" redefined In file included from include/linux/spinlock.h:90, from include/linux/kobject.h:23, from include/linux/device.h:16, from include/linux/genhd.h:15, from include/linux/blkdev.h:6, from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:1: include/linux/spinlock_up.h:61:1: warning: this is the location of the previous definition In file included from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:7: include/asm/spinlock.h:51: error: syntax error before 'do' include/asm/spinlock.h: In function '__raw_spin_lock_flags': include/asm/spinlock.h:62: error: 'struct <anonymous>' has no member named 'slock' include/asm/spinlock.h:60: error: invalid lvalue in asm output 0 include/asm/spinlock.h: At top level: include/asm/spinlock.h:65: error: syntax error before '{' token include/asm/spinlock.h:89: error: syntax error before 'do' In file included from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:7: include/asm/spinlock.h:114:1: warning: "__raw_spin_unlock_wait" redefined In file included from include/linux/spinlock.h:90, from include/linux/kobject.h:23, from include/linux/device.h:16, from include/linux/genhd.h:15, from include/linux/blkdev.h:6, from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:1: include/linux/spinlock_up.h:71:1: warning: this is the location of the previous definition In file included from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:7: include/asm/spinlock.h:142:1: warning: "__raw_read_can_lock" redefined In file included from include/linux/spinlock.h:90, from include/linux/kobject.h:23, from include/linux/device.h:16, from include/linux/genhd.h:15, from include/linux/blkdev.h:6, from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:1: include/linux/spinlock_up.h:68:1: warning: this is the location of the previous definition In file included from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:7: include/asm/spinlock.h:148:1: warning: "__raw_write_can_lock" redefined In file included from include/linux/spinlock.h:90, from include/linux/kobject.h:23, from include/linux/device.h:16, from include/linux/genhd.h:15, from include/linux/blkdev.h:6, from /home/dirk/Masterarbeit/mynoop/test/mynoop.c:1: include/linux/spinlock_up.h:69:1: warning: this is the location of the previous definition include/asm/spinlock.h: In function '__raw_read_unlock': include/asm/spinlock.h:181: error: 'struct <anonymous>' has no member named 'lock' include/asm/spinlock.h:181: error: invalid lvalue in asm output 0 include/asm/spinlock.h: In function '__raw_write_unlock': include/asm/spinlock.h:187: error: 'struct <anonymous>' has no member named 'lock' include/asm/spinlock.h:186: error: invalid lvalue in asm output 0
shouldn't it be possible to use spinlocks in my code even if I don't support SMP for compatiblity ?
