Does every nfs_read always has a nfs_readpage request or does both are exclusive? Please explain.

I am trying to understand this: http://www.fsl.cs.stonybrook.edu/~mchen/mountstat-format.txt

  • The file you link to doesn't mention either nfs_read or nfs_readpage; could you expand your question a little? E.g. explain what led you to nfs_read, nfs_readpage... – Stephen Kitt Oct 27 '16 at 11:11
  • @StephenKitt Hi, thanks for asking. I read it here: git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/… see the definition of: fs_stat_bytecounters and I have understood all variables except that NFSIOS_READPAGES and NFSIOS_WRITEPAGES – GP92 Oct 27 '16 at 12:29
