RHBZ: 1795429
In recent DFS updates we have a new variable controlling how many times we will
retry to reconnect the share.
If DFS is not used, then this variable is initialized to 0 in:
static inline int
dfs_cache_get_nr_tgts(const struct dfs_cache_tgt_list *tl)
{
return tl ? tl->tl_numtgts : 0;
}
This means that in the reconnect loop in smb2_reconnect() we will immediately wrap retries to -1
and never actually get to pass this conditional:
if (--retries)
continue;
The effect is that we no longer reach the point where we fail the commands with -EHOSTDOWN
and basically the kernel threads are virtually hung and unkillable.
Fixes: a3a53b7603798fd8 (cifs: Add support for failover in smb2_reconnect())
