Subject: [PATCH net-next 0/6] net: core: remove TX_LOCKED support
Date: Sun, 24 Apr 2016 21:38:08 +0200 [thread overview]
Message-ID: <1461526694-11367-1-git-send-email-fw@strlen.de> (raw)
Not that many users left, lets kill it.
TX_LOCKED was meant to be used by LLTX drivers when spin_trylock()
failed. Stack then re-queued if collisions happened on different
cpus or free'd the skb to prevent deadlocks.
Most of the driver removal patches fall into one of three categories:
1. remove the driver-private tx lock (and LLTX flag), or...
2. convert spin_trylock to plain spin_lock, or...
3. convert TX_LOCKED to free+TX_OK
Patches are grouped by these categories, last patch is the actual removal.
All driver changes were compile tested only with exception of atl1e.
