Dzsmalloc.rst10 any object of size PAGE_SIZE/2 or larger would occupy an entire page.
11 This was one of the major issues with its predecessor (xvmalloc).
13 To overcome these issues, zsmalloc allocates a bunch of 0-order pages
19 For simplicity, zsmalloc can only allocate objects of size up to PAGE_SIZE
20 since this satisfies the requirements of all its current users (in the

40 The advantage of one over the other is that the sysfs choice works well

42 be a better choice if you are watching a large number of disks because
