that I have access to. I should also note that installing pvfs2 from source works fine on both machines. It seems that a configure variable is somehow getting reset. For instance, in /var/tmp/portage/sys-cluster/pvfs2-2.7.0/work/pvfs-2.7.0/maint/config/kernel.m4 line 441: "AC_DEFINE(HAVE_VFSMOUNT_GETSB, 1, Define if get_sb callback has struct vfsmount argument)," has the variable "HAVE_VFSMOUNT_GETSB" correct. It seems to be set to 0 somewhere later on during make which causes the calls to the wrong version of get_sb_nodev.
Relevant block from config.log. We've confirmed that this test does pass (as it should) if -Wno-strict-aliasing=2 is removed from the compile line. I'm working on a fix for the ebuild now, but just wanted to have this recorded here. configure:9538: checking if get_sb callback in kernel has struct vfsmount argument configure:9569: i686-pc-linux-gnu-gcc -c -O2 -march=i686 -pipe -Werror-implicit-function-declaration -nostdinc -isystem /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/include -I/usr/src/linux/include -I/usr/src/linux/include/asm/mach-default -DKBUILD_STR(s)=#s -DKBUILD_BASENAME=KBUILD_STR(empty) -DKBUILD_MODNAME=KBUILD_STR(empty) -imacros /usr/src/linux/include/linux/autoconf.h -Werror -Wno-pointer-sign -Wno-strict-aliasing -Wno-strict-aliasing=2 conftest.c >&5 cc1: warnings being treated as errors In file included from /usr/src/linux/include/asm/system.h:7, from /usr/src/linux/include/asm/processor.h:18, from /usr/src/linux/include/linux/prefetch.h:14, from /usr/src/linux/include/linux/list.h:8, from /usr/src/linux/include/linux/wait.h:22, from /usr/src/linux/include/linux/fs.h:272, from conftest.c:42: /usr/src/linux/include/asm/cmpxchg.h: In function '__set_64bit_var': /usr/src/linux/include/asm/cmpxchg.h:57: warning: dereferencing type-punned pointer will break strict-aliasing rules /usr/src/linux/include/asm/cmpxchg.h:57: warning: dereferencing type-punned pointer will break strict-aliasing rules configure:9575: $? = 1 configure: failed program was: | /* confdefs.h. */ | #define PACKAGE_NAME "" | #define PACKAGE_TARNAME "" | #define PACKAGE_VERSION "" | #define PACKAGE_STRING "" | #define PACKAGE_BUGREPORT "" | #define PVFS2_VERSION_MAJOR 2 | #define PVFS2_VERSION_MINOR 7 | #define PVFS2_VERSION_SUB 0 | #define STDC_HEADERS 1 | #define HAVE_SYS_TYPES_H 1 | #define HAVE_SYS_STAT_H 1 | #define HAVE_STDLIB_H 1 | #define HAVE_STRING_H 1 | #define HAVE_MEMORY_H 1 | #define HAVE_STRINGS_H 1 | #define HAVE_INTTYPES_H 1 | #define HAVE_STDINT_H 1 | #define HAVE_UNISTD_H 1 | #define HAVE_SYS_VFS_H 1 | #define HAVE_SYS_MOUNT_H 1 | #define HAVE_FSTAB_H 1 | #define HAVE_STDARG_H 1 | #define HAVE_ATTR_XATTR_H 1 | #define HAVE_SYS_XATTR_H 1 | #define SIZEOF_LONG_INT 4 | #define WITH_OPENSSL 1 | #define HAVE_OPENSSL_EVP_H 1 | #define HAVE_OPENSSL_CRYPTO_H 1 | #define SIZEOF_VOID_P 4 | #define HAVE_I_SIZE_WRITE 1 | #define HAVE_I_SIZE_READ 1 | #define HAVE_IGET_LOCKED 1 | #define HAVE_IGET5_LOCKED 1 | #define HAVE_STRUCT_KMEM_CACHE 1 | #define HAVE_AIO 1 | #define HAVE_AIO_VFS_SUPPORT 1 | #define HAVE_AIO_NEW_AIO_SIGNATURE 1 | /* end confdefs.h. */ | | #define __KERNEL__ | #include <linux/fs.h> | #include <linux/mount.h> | extern int pvfs_get_sb(struct file_system_type *fst, int flags, const char *devname, void *data, struct vfsmount *); | static struct file_system_type fst = { | .get_sb = pvfs_get_sb, | }; | | int | main () | { | fst.get_sb = 0; | ; | return 0; | }
Fixed in 2.7.0-r1 which I just committed to cvs. Thanks for the report.
