From 46385326cc1577587ed3e7432c2425cf6d3e4308 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 13 Feb 2015 14:38:15 -0800 Subject: bitmap, cpumask, nodemask: remove dedicated formatting functions Now that all bitmap formatting usages have been converted to '%*pb[l]', the separate formatting functions are unnecessary. The following functions are removed. * bitmap_scn[list]printf() * cpumask_scnprintf(), cpulist_scnprintf() * [__]nodemask_scnprintf(), [__]nodelist_scnprintf() * seq_bitmap[_list](), seq_cpumask[_list](), seq_nodemask[_list]() * seq_buf_bitmask() Signed-off-by: Tejun Heo Cc: Rusty Russell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- lib/bitmap.c | 41 ----------------------------------------- lib/seq_buf.c | 36 ------------------------------------ 2 files changed, 77 deletions(-) (limited to 'lib') diff --git a/lib/bitmap.c b/lib/bitmap.c index 088adbd..d456f4c1 100644 --- a/lib/bitmap.c +++ b/lib/bitmap.c @@ -370,24 +370,6 @@ EXPORT_SYMBOL(bitmap_find_next_zero_area_off); #define BASEDEC 10 /* fancier cpuset lists input in decimal */ /** - * bitmap_scnprintf - convert bitmap to an ASCII hex string. - * @buf: byte buffer into which string is placed - * @buflen: reserved size of @buf, in bytes - * @maskp: pointer to bitmap to convert - * @nmaskbits: size of bitmap, in bits - * - * Exactly @nmaskbits bits are displayed.
