From: Jiri Slaby Date: Mon, 24 Feb 2014 18:59:57 +0000 (+0100) Subject: ftrace: Inline the code from ftrace_dyn_table_alloc() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c867ccd8388d1c1a31bef9c54544b2ef32f0ebca;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ftrace: Inline the code from ftrace_dyn_table_alloc() The function used to do allocations some time ago. 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 Link: http://lkml.kernel.org/r/1393268401-24379-2-git-send-email-jslaby@suse.cz Signed-off-by: Jiri Slaby Cc: Frederic Weisbecker Cc: Ingo Molnar Signed-off-by: Steven Rostedt --- 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;
