pnfs/flexfiles: Fix PTR_ERR() dereferences in ff_layout_track_ds_error

2019-07-26T07:12:58Z

commit 8e04fdfadda75a849c649f7e50fe7d97772e1fcb upstream. mirror->mirror_ds can be NULL if uninitialised, but can contain a PTR_ERR() if call to GETDEVICEINFO failed.

NFS/flexfiles: Use the correct TCP timeout for flexfiles I/O

2019-07-03T11:13:39Z

commit 68f461593f76bd5f17e87cdd0bea28f4278c7268 upstream. Fix a typo where we're confusing the default TCP retrans value (NFS_DEF_TCP_RETRANS) for the default TCP timeout value.

pNFS/flexfiles: Fix layoutstats handling during read failovers

2019-03-23T16:03:58Z

During a read failover, we may end up changing the value of the pgio_mirror_idx, so make sure that we record the layout stats before that update. Signed-off-by: Trond Myklebust

NFS/flexfiles: Clean up mirror DS initialisation

2019-03-02T03:37:39Z

Get rid of the redundant parameter and rename the function ff_layout_mirror_valid() to ff_layout_init_mirror_ds() for clarity. Signed-off-by: Trond Myklebust

NFS/flexfiles: Remove dead code in ff_layout_mirror_valid()

2019-03-02T03:37:38Z

nfs4_ff_alloc_deviceid_node() guarantees that if mirror->mirror_ds is a valid pointer, then so is mirror->mirror_ds->ds. Signed-off-by: Trond Myklebust

NFS/flexfile: Simplify nfs4_ff_layout_select_ds_stateid()

2019-03-02T03:37:38Z

Pass in a pointer to the mirror rather than forcing another array access. Signed-off-by: Trond Myklebust

2019-03-02T03:37:38Z

2019-03-02T03:37:38Z

Pass in a pointer to the mirror rather than having to retrieve it from the array and then verify the resulting pointer. Signed-off-by: Trond Myklebust
