Re: whats the difference between "normal pages" and "buffer pages" in Page Cache?

Hi Adheer

happy new year

basically, "buffer" holds the metadata parts, that is superblock,
directory and inodes and other kinds of metadata (journal maybe?)

On the other hand, "page cache" hold the content...that is the data
inside the file.

For the operation, AFAIK doing read() make the contents goes to page
cache, while functions like bread() make the data goes to buffer.

Somebody please CMIIW.

regards,

Mulyadi
