Hi. The 64 in the page buffer represents 64 virtual pages. In 80b, 64b represents a 64-bit bitmap, what do the remaining 16b represent?

I browsed the source code but did not understand the function of the 16b. I guess the 16b is related to ocp_perc_page_buf_assoc, but I'm not sure where the 16b is used. @rahulbera
