Subject: [PATCH 0/6] Sanity checks for ERR_PTR argument
Date: Sun, 18 May 2008 23:56:52 +0200 [thread overview]
Message-ID: <1211147818-16056-1-git-send-email-marcin.slusarz@gmail.com> (raw)
In-Reply-To: <20080513201813.GA5869@joi>
This little patchset adds sanity checks to ERR_PTR.
[PATCH 1/6] ERR_PTR: if errno value is known at compile time, make sure it's valid
[PATCH 2/6] ERR_PTR: add ERR_OR_0_PTR
[PATCH 3/6] vfs: open_exec cleanup
[PATCH 4/6] procfs: switch ERR_PTR to ERR_OR_0_PTR when "error" might be 0
[PATCH 5/6] vfs: fix ERR_PTR abuse in generic_readlink
[PATCH 6/6] ERR_PTR: warn when ERR_PTR parameter is not errno value
The most important are patches 1 and 6. 2nd patch adds another ERR_PTR-like helper.
The rest (3-5) fix false positives found by 6th patch.
