tools/mm: fix undefined reference to pthread_once

2023-09-05T17:13:45+00:00

Commit 97d5f2e9ee12 ("tools api fs: More thread safety for global filesystem variables") introduces pthread_once, so the libpthread should be added at link time, or we'll meet the following compile error when 'make -C tools/mm': gcc -Wall -Wextra -I../lib/ -o page-types page-types.c ../lib/api/libapi.a ~/linux/tools/lib/api/fs/fs.c:146: undefined reference to `pthread_once' ~/linux/tools/lib/api/fs/fs.c:147: undefined reference to `pthread_once' ~/linux/tools/lib/api/fs/fs.c:148: undefined reference to `pthread_once' ~/linux/tools/lib/api/fs/fs.c:149: undefined reference to `pthread_once' ~/linux/tools/lib/api/fs/fs.c:150: undefined reference to `pthread_once' /usr/bin/ld: ../lib/api/libapi.a(libapi-in.o):~/linux/tools/lib/api/fs/fs.c:151: more undefined references to `pthread_once' follow collect2: error: ld returned 1 exit status make: *** [Makefile:22: page-types] Error 1 Link: https://lkml.kernel.org/r/20230831034205.2376653-1-xiexiuqi@huaweicloud.com Fixes: 97d5f2e9ee12 ("tools api fs: More thread safety for global filesystem variables") Signed-off-by: Xie XiuQi Acked-by: Ian Rogers Cc: Matthew Wilcox Signed-off-by: Andrew Morton

tools/mm: allow users to provide additional cflags/ldflags

2023-02-03T06:33:24+00:00

Right now there is no way to provide additional cflags/ldflags when building tools/vm binaries. And using eg. make CFLAGS= will override the CFLAGS being set in the Makefile, making the build fail since it requires the include of the ../lib dir (for libapi). This change then allows you to specify: CFLAGS= LDFLAGS= make V=1 -C tools/vm And the options will be correctly appended as can be seen from the make output.

tools/vm: rename tools/vm to tools/mm

2023-01-19T01:12:55+00:00

Rename tools/vm to tools/mm for being more consistent with the code and documentation directories, and won't be confused with virtual machines.
