The patch titled Subject: memblock: neaten logging has been added to the -mm tree. Its filename is memblock-neaten-logging.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/memblock-neaten-logging.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/memblock-neaten-logging.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Joe Perches <joe@xxxxxxxxxxx> Subject: memblock: neaten logging Use more typical kernel logging styles. o Add and use #define pr_fmt KBUILD_MODNAME ": " fmt o Neaten memblock_dbg to use %s: %pS: to output __func__ and caller o Convert existing uses of pr_<level> and memblock_dbg appropriately Logging output is now always prefixed with 'memblock: ' Debugging output is now prefixed with 'memblock: ', function and caller Link: https://lkml.kernel.org/r/623750dd31aa3fe5e45c416be98ab37707e2c45d.camel@xxxxxxxxxxx Signed-off-by: Joe Perches <joe@xxxxxxxxxxx> Cc: Mike Rapoport <rppt@xxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/memblock.c | 59 +++++++++++++++++++++--------------------------- 1 file changed, 26 insertions(+), 33 deletions(-) --- a/mm/memblock.c~memblock-neaten-logging +++ a/mm/memblock.c @@ -6,6 +6,8 @@ * Copyright (C) 2001 Peter Bergner. */ +#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt + #include <linux/kernel.h> #include <linux/slab.h> #include <linux/init.h> @@ -146,10 +148,12 @@ static __refdata struct memblock_type *m i++, rgn = &memblock_type->regions[i]) #define memblock_dbg(fmt, ...) \ - do { \ - if (memblock_debug) \ - pr_info(fmt, ##__VA_ARGS__); \ - } while (0) +do { \ + if (memblock_debug) \ + pr_info("%s: %pS: " fmt, \ + __func__, __builtin_return_address(0), \ + ##__VA_ARGS__); \ +} while (0) static int memblock_debug __initdata_memblock; static bool system_has_some_mirror __initdata_memblock = false; @@ -447,14 +451,14 @@ static int __init_memblock memblock_doub new_array = addr ?
