Subject: [PATCH 4.9 11/14] scripts/decode_stacktrace: match basepath using shell prefix operator, not regex
Date: Fri, 13 Sep 2019 14:07:04 +0100	[thread overview]
Message-ID: <20190913130446.021198073@linuxfoundation.org> (raw)
In-Reply-To: <20190913130440.264749443@linuxfoundation.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")
