Subject: [PATCH AUTOSEL 4.4 4/6] scripts/decode_stacktrace: match basepath using shell prefix operator, not regex
Date: Thu, 29 Aug 2019 06:51:08 -0400 [thread overview]
Message-ID: <20190829105110.2748-4-sashal@kernel.org> (raw)
In-Reply-To: <20190829105110.2748-1-sashal@kernel.org>
From: Nicolas Boichat <drinkcat@chromium.org>
[ Upstream commit 31013836a71e07751a6827f9d2ad41ef502ddaff ]
The basepath may contain special characters, which would confuse the regex
matcher. ${var#prefix} does the right thing.

Fixes: 67a28de47faa8358 ("scripts/decode_stacktrace: only strip base path when a prefix of the path")
