All callers of d_alloc_parallel() must make sure that resulting in-lookup dentry (if any) will encounter __d_lookup_done() before the final dput(). d_add_ci() might end up creating in-lookup dentries; they are fed to d_splice_alias(), which will normally make sure they meet __d_lookup_done(). However, it is possible to end up with d_splice_alias() failing with ERR_PTR(-ELOOP) without having done so. It takes a corrupted ntfs or case-insensitive xfs image, but neither should end up with memory corruption... Signed-off-by: Al Viro <[email protected]>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
