This no longer happens and it only checks the count and prints some info. This patch inlines the body to the only caller. There are two reasons: * the name of the function was misleading * it's clear what is going on in ftrace_init now Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> --- kernel/trace/ftrace.c | 25 ++++++------------------- 1 file changed, 6 insertions(+), 19 deletions(-) diff --git a/kernel/trace/ftrace.c b/kernel/trace/ftrace.c index 3f95bbeb8e8d..76b6ed29d856 100644 --- a/kernel/trace/ftrace.c +++ b/kernel/trace/ftrace.c @@ -2465,22 +2465,6 @@ ftrace_allocate_pages(unsigned long num_to_init) return NULL; } -static int __init ftrace_dyn_table_alloc(unsigned long num_to_init) -{ - int cnt; - - if (!num_to_init) { - pr_info("ftrace: No functions to be traced?\n"); - return -1; - } - - cnt = num_to_init / ENTRIES_PER_PAGE; - pr_info("ftrace: allocating %ld entries in %d pages\n", - num_to_init, cnt + 1); - - return 0; -} - #define FTRACE_BUFF_MAX (KSYM_SYMBOL_LEN+4) /* room for wildcards */ struct ftrace_iterator { @@ -4403,10 +4387,13 @@ void __init ftrace_init(void) goto failed; count = __stop_mcount_loc - __start_mcount_loc; - - ret = ftrace_dyn_table_alloc(count); - if (ret) + if (!count) { + pr_info("ftrace: No functions to be traced?\n"); goto failed; + } + + pr_info("ftrace: allocating %ld entries in %ld pages\n", + count, count / ENTRIES_PER_PAGE + 1); last_ftrace_enabled = ftrace_enabled = 1; -- 1.8.5.2
