The functions get_order and is_power_of_2 are simple and should probably be in a header, like similar simple functions in bitops.h Since they concern bit manipulation, the logical place for them is in bitops.h Signed-off-by: Claudio Imbrenda <imbrenda@xxxxxxxxxxxxx> Reviewed-by: Andrew Jones <drjones@xxxxxxxxxx> --- lib/alloc_page.h | 1 - lib/bitops.h | 10 ++++++++++ lib/libcflat.h | 5 ----- lib/alloc.c | 1 + lib/alloc_page.c | 5 ----- 5 files changed, 11 insertions(+), 11 deletions(-) diff --git a/lib/alloc_page.h b/lib/alloc_page.h index d9aceb7..88540d1 100644 --- a/lib/alloc_page.h +++ b/lib/alloc_page.h @@ -15,6 +15,5 @@ void *alloc_pages(unsigned int order); void free_page(void *page); void free_pages(void *mem, size_t size); void free_pages_by_order(void *mem, unsigned int order); -unsigned int get_order(size_t size); #endif diff --git a/lib/bitops.h b/lib/bitops.h index b310a22..308aa86 100644 --- a/lib/bitops.h +++ b/lib/bitops.h @@ -74,4 +74,14 @@ static inline unsigned long fls(unsigned long word) } #endif +static inline bool is_power_of_2(unsigned long n) +{ + return n && !(n & (n - 1)); +} + +static inline unsigned int get_order(size_t size) +{ + return size ? fls(size) + !is_power_of_2(size) : 0; +} + #endif diff --git a/lib/libcflat.h b/lib/libcflat.h index 7092af2..ec0f58b 100644 --- a/lib/libcflat.h +++ b/lib/libcflat.h @@ -147,11 +147,6 @@ do { \ } \ } while (0) -static inline bool is_power_of_2(unsigned long n) -{ - return n && !(n & (n - 1)); -} - /* * One byte per bit, a ' between each group of 4 bits, and a null terminator. */ diff --git a/lib/alloc.c b/lib/alloc.c index 6c89f98..9d89d24 100644 --- a/lib/alloc.c +++ b/lib/alloc.c @@ -1,4 +1,5 @@ #include "alloc.h" +#include "bitops.h" #include "asm/page.h" #include "bitops.h" diff --git a/lib/alloc_page.c b/lib/alloc_page.c index f16eaad..fa3c527 100644 --- a/lib/alloc_page.c +++ b/lib/alloc_page.c @@ -175,8 +175,3 @@ void page_alloc_ops_enable(void) { alloc_ops = &page_alloc_ops; } - -unsigned int get_order(size_t size) -{ - return is_power_of_2(size) ? fls(size) : fls(size) + 1; -} -- 2.26.2
