rb_check_pages

函数名称：_check_pages - integrity check of buffer pages*@cpu_buffer: CPU buffer with pages to test* As a safety measure we check to make sure the data pages have not* been corrupted.

函数原型：static int rb_check_pages(struct ring_buffer_per_cpu *cpu_buffer)

返回类型：int

参数：

类型	参数	名称
struct ring_buffer_per_cpu *	cpu_buffer

1156

head等于pages

1160

如果ad from head 则rb_set_head_page(cpu_buffer)

1163

_head_page_deactivate - clears head page ptr (for free list)

1165

如果uffer may be either ring_buffer or ring_buffer_per_cpu (cpu_buffer, 链表前项 != head)则返回:负1

1167

如果uffer may be either ring_buffer or ring_buffer_per_cpu (cpu_buffer, 链表后项 != head)则返回:负1

1170

如果_check_list - make sure a pointer to a list has the last bits zero则返回:负1

1174

如果uffer may be either ring_buffer or ring_buffer_per_cpu (cpu_buffer, 链表前项 != & list of buffer pages )则返回:负1

1177

如果uffer may be either ring_buffer or ring_buffer_per_cpu (cpu_buffer, 链表后项 != & list of buffer pages )则返回:负1

1180

如果_check_list - make sure a pointer to a list has the last bits zero则返回:负1

1184

_head_page_activate - sets up head page

1186

返回:0

rb_allocate_pages
ring_buffer_resize	g_buffer_resize - resize the ring buffer@buffer: the buffer to resize.@size: the new size.@cpu_id: the cpu buffer to resize Minimum size is 2 * BUF_PAGE_SIZE.* Returns 0 on success and < 0 on failure.
ring_buffer_read_finish	g_buffer_read_finish - finish reading the iterator of the buffer@iter: The iterator retrieved by ring_buffer_start This re-enables the recording to the buffer, and frees the* iterator.
