Subject: [PATCH v7 00/21] client and server support for "inter" SSC copy
Date: Fri, 6 Sep 2019 19:35:50 -0400 [thread overview]
Message-ID: <20190906233611.4031-1-olga.kornievskaia@gmail.com> (raw)
From: Olga Kornievskaia <kolga@netapp.com>
As per Bruce's request submitting the client and server series together
as there is a common patch that's needed by both.
v7
--- added new patch (11/21) that checks the size of the file and
decides to either do a sync intra, or not do inter at all and fallback
on traditional copy.
v6 server-side changes
--- removed global copy notify list and instead relying only on the idr
list of stateids. Laundromat now traverses that list and if copy notify
state wasn't referenced in a lease period, state is deleted.
--- removed storing parent's stid pointer in the copy notify state.
instead storing the parent's stateid and client id then using it to
lookup the stid structure and client structure during validation of
the stateid of the READ.
--- added a refcount to the copy notify state to make sure only 1 will
delete it (as it can be delete either by the nfs4_put_stid(),
laundromat, or offload_cancel op. basically all access to the copy state
is using just one global lock now (netd->s2s_cp_lock).
--- added a type to the copy_stateid_t to distinguish copy notify state
kept by the source server and copy state used by the destination server.
--- previously with a global copy notify list, the check if client has
state before unmounting checked if the list was empty, now the code
traverses the idr list and looks for anything with a matching clientid
(again under the global s2s_cp_lock).
