What is the time complexity of find_get_pages_tag?
Clash Royale CLAN TAG#URR8PPP
I am required to find the dirty pages in some offset range, so I am using find_get_pages_tag() for it, but I am concerned about its complexity since this call would be called multiple times from my code. I looked through the definition of this function on bootlin, seems worst case is O(n). Is this correct?
My kernel release is
2.6.32-754.3.5.el6.x86_64
linux filesystems rhel linux-kernel
