| |
Latest git compiles with extreme noise:
In file included from include/net/inet_connection_sock.h:23, from include/linux/tcp.h:178, from include/linux/ipv6.h:215, from include/net/ipv6.h:16, from include/linux/sunrpc/clnt.h:25, from include/linux/nfs_fs.h:52, from kernel/sysctl.c:48: include/net/inet_sock.h: In function 'inet_reqsk_alloc': include/net/inet_sock.h:208: warning: ISO C90 forbids mixed declarations and code
Vegard, this is obviously caused by commit 45e3ff82708c65c895d5c5882aff17ecf62a80b5.
$ grep KMEMCH .config CONFIG_HAVE_ARCH_KMEMCHECK=y
(I.e. CONFIG_KMEMCHECK is off.)
More kmemcheck bogosity:
CC net/core/skbuff.o In file included from include/net/ip.h:30, from include/linux/errqueue.h:27, from net/core/skbuff.c:59: include/net/inet_sock.h: In function 'inet_reqsk_alloc': include/net/inet_sock.h:208: warning: ISO C90 forbids mixed declarations and code net/core/skbuff.c: In function '__alloc_skb': net/core/skbuff.c:205: warning: ISO C90 forbids mixed declarations and code net/core/skbuff.c:206: warning: ISO C90 forbids mixed declarations and code net/core/skbuff.c:227: warning: ISO C90 forbids mixed declarations and code net/core/skbuff.c:228: warning: ISO C90 forbids mixed declarations and code net/core/skbuff.c: In function 'skb_clone': net/core/skbuff.c:645: warning: ISO C90 forbids mixed declarations and code net/core/skbuff.c:646: warning: ISO C90 forbids mixed declarations and code
This one is older:
CC net/ethernet/eth.o [...kmemcheck noise from inet_sock.h:208, and then...:] net/ethernet/eth.c: At top level: net/ethernet/eth.c:402: warning: 'print_mac' is deprecated (declared at net/ethernet/eth.c:398) net/ethernet/eth.c:402: warning: 'print_mac' is deprecated (declared at net/ethernet/eth.c:398)
Obviously added by b5eb0589937eae2d58fca17fa45ed44152e772ed. Johannes, can't the __deprecated logic be suppressed when print_mac is used in EXPORT_SYMBOL?
Next one:
CC mm/mmap.o mm/mmap.c: In function 'do_mmap_pgoff': mm/mmap.c:953: warning: unused variable 'user'
Eric, this was added by 4e52780d41a741fb4861ae1df2413dd816ec11b1.
$ grep HUGETLB .config # CONFIG_HUGETLBFS is not set # CONFIG_HUGETLB_PAGE is not set
Next one:
CC [M] drivers/gpu/drm/radeon/radeon_ttm.o drivers/gpu/drm/radeon/radeon_ttm.c: In function 'radeon_ttm_debugfs_init': drivers/gpu/drm/radeon/radeon_ttm.c:714: warning: unused variable 'i' drivers/gpu/drm/radeon/radeon_ttm.c: At top level: drivers/gpu/drm/radeon/radeon_ttm.c:692: warning: 'radeon_mem_types_list' defined but not used drivers/gpu/drm/radeon/radeon_ttm.c:693: warning: 'radeon_mem_types_names' defined but not used
Dave, added by fa8a123855e20068204982596b8fafceb1a67f0b.
