Hi Greg 6.2.7-rc1 compiles [1], boots and runs here on x86_64 (Intel i5-11400, Fedora 38 Beta) Thanks Tested-by: Ronald Warsow <rwarsow@xxxxxx> [1] compiles *not* without warnings since compiler version change from Fedora 37 => Fedora 38 *Beta* It's *not* a regression from kernel 6.2.6 => 6.2.7-rc1 ! cause I'm no developer I can't decide what it is: code or compiler. anyway I I filled a Red Hat bug report: https://bugzilla.redhat.com/show_bug.cgi?id=2178317 and place the warnings here in case it is coding. if so, please let me know, so I could suggest to close the bug report ! compilers ========= F38: gcc version 13.0.1 20230310 (Red Hat 13.0.1-0) (GCC) F37: gcc-12.2.1-4.fc37 output compiling 6.2.7-rc1 ========================== CC fs/f2fs/file.o In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_disk_total’ at fs/btrfs/sysfs.c:836:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -35 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_bytes_may_use’ at fs/btrfs/sysfs.c:832:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -44 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_bytes_readonly’ at fs/btrfs/sysfs.c:833:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -43 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_bytes_zone_unusable’ at fs/btrfs/sysfs.c:834:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -41 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_disk_used’ at fs/btrfs/sysfs.c:835:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -36 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_flags’ at fs/btrfs/sysfs.c:827:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -34 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_total_bytes’ at fs/btrfs/sysfs.c:828:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -48 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_bytes_used’ at fs/btrfs/sysfs.c:829:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -47 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_bytes_pinned’ at fs/btrfs/sysfs.c:830:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -46 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ In function ‘btrfs_show_u64’, inlined from ‘btrfs_space_info_show_bytes_reserved’ at fs/btrfs/sysfs.c:831:1: fs/btrfs/sysfs.c:636:13: warning: array subscript -45 is outside array bounds of ‘struct kobject[144115188075855871]’ [-Warray-bounds=] 636 | val = *value_ptr; | ~~~~^~~~~~~~~~~~ ...
