With this patch, there will be additional entries seen in
the profile info:
UPCALL : Total number of upcall events that were sent from
the brick(in brick profile), and number of upcall
notifications recieved by client(in client profile)
Cache invalidation events:
-------------------------
CI_IATT : Number of upcalls that were cache invalidation and
had one of the IATT_UPDATE_FLAGS set. This indicates
that one of the iatt value was changed.
CI_XATTR : Number of upcalls that were cache invalidation, and
had one of the UP_XATTR or UP_XATTR_RM set. This indicates
that an xattr was updated or deleted.
CI_RENAME : Number of upcalls that were cache invalidation,
resulted by the renaming of a file or directory
CI_UNLINK : Number of upcalls that were cache invalidation,
resulted by the unlink of a file.
CI_FORGET : Number of upcalls that were cache invalidation,
resulted by the forget of inode on the server side.
Lease events:
------------
LEASE_RECALL : Number of lease recalls sent by the brick (in
brick profile), and number of lease recalls recieved
by client(in client profile)
Note that the sum of CI_IATT, CI_XATTR, CI_RENAME, CI_UNLINK,
CI_FORGET, LEASE_RECALL may not be equal to UPCALL. This is
because, each cache invalidation can carry multiple flags.
Eg:
- Every CI_XATTR will have CI_IATT
- Every CI_UNLINK will also increment CI_IATT as link count is an
iatt attribute.
Also UP_PARENT_DENTRY_FLAGS is currently not accounted for,
as CI_RENAME and CI_UNLINK will always have the flag
UP_PARENT_DENTRY_FLAGS
