Subject: [PATCH 02/29] xfs: rename XBF_TRYLOCK to XBF_NOWAIT
Date: Fri, 25 Aug 2023 21:54:04 +0800	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

From: Hao Xu <[email protected]>

XBF_TRYLOCK means we need lock but don't block on it, we can use it to
stand for not waiting for memory allcation. Rename XBF_TRYLOCK to
XBF_NOWAIT, which is more generic.
