Hi all,
After merging the vfs-brauner tree, today's linux-next build (powerpc
allyesconfig) produced these warnings:

I am not sure why these warnings only turned up today.

I'm not sure how to fix this the right way.
The problem seems to be a discrepancy in the __u64 type between arches.
Changing these in a way that would make PPC happy causes these warnings
on x86_64:
gcc -Wp,-MMD,./.mountinfo.d -Wall -Wmissing-prototypes -Wstrict-prototypes -O2 -fomit-frame-pointer -std=gnu11 -m64 -I usr/include -m64 -o mountinfo mountinfo.c
mountinfo.c: In function ‘show_propagation’:
mountinfo.c:104:35: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘__u64’ {aka ‘long long unsigned int’} [-Wformat=]
104 | printf(" shared:%lu", sm->mnt_peer_group);
| ~~^ ~~~~~~~~~~~~~~~~~~
| | |
| | __u64 {aka long long unsigned int}
| long unsigned int
| %llu
mountinfo.c:106:35: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘__u64’ {aka ‘long long unsigned int’} [-Wformat=]
106 | printf(" master:%lu", sm->mnt_master);
| ~~^ ~~~~~~~~~~~~~~
| | |
| | __u64 {aka long long unsigned int}
| long unsigned int
| %llu
mountinfo.c:108:51: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘__u64’ {aka ‘long long unsigned int’} [-Wformat=]
108 | printf(" propagate_from:%lu", sm->propagate_from);
| ~~^ ~~~~~~~~~~~~~~~~~~
| | |
| | __u64 {aka long long unsigned int}
| long unsigned int
| %llu
mountinfo.c: In function ‘dump_mountinfo’:
mountinfo.c:144:41: warning: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘__u64’ {aka ‘long long unsigned int’} [-Wformat=]
144 | printf("0x%lx 0x%lx 0x%lx ", mnt_ns_id, mnt_id, buf->mnt_parent_id);
| ~~^ ~~~~~~~~~~~~~~~~~~
| | |
| long unsigned int __u64 {aka long long unsigned int}
| %llx
What format specifier should we be using that would make both arches happy?
Thanks,

Which is now used by samples/vfs/mountinfo.c...
However, it's still broken on 32-bit. I have sent a fix.

Can __refdata (or __refconst) be used on initramfs_test_cases?

Hi all,
After merging the vfs-brauner tree, today's linux-next build (htmldocs)
produced these warnings:
include/linux/fs.h:1071: warning: Function parameter or struct member 'f_ref' not described in 'file'
include/linux/fs.h:1071: warning: Excess struct member 'f_count' description in 'file'
Introduced by commit
3488e37e1059 ("fs: port files to file_ref")

Cheers,
