Hi,
I can't build jfs in 2.5.6 with gcc 2.95.4 from Debian
testing:
gcc -D__KERNEL__ -I/home/matthew/kern/linux-2.5.6/include -Wall
-Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer
-fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2
-march=k6 -D_JFS_4K -DKBUILD_BASENAME=jfs_imap -c -o jfs_imap.o
jfs_imap.c
jfs_imap.c: In function `diAlloc':
/home/matthew/kern/linux-2.5.6/include/asm/rwsem.h:169: inconsistent
operand constraints in an `asm'
jfs_imap.c: In function `diNewIAG':
/home/matthew/kern/linux-2.5.6/include/asm/rwsem.h:169: inconsistent
operand constraints in an `asm'
I don't really speak gcc asm, so I don't know where to start
on this. Is it a known issue?
Matthew.

Builds for me, too. Are you sure that constraint
isn't useful?
