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

Currently when a client performs a readdirp it is not stored
in upcall, as one of the clients that have accessed the files.
Hence, when any other client modifies the file, the client that
had performed readdirp will not get any notifications.
Fix this by adding the clients to upcall database when they
perform readdirp.
