Linux kernel source tree
98ea203287
The kernel memory leak detector located the following:
unreferenced object 0xffff95d941135b50 (size 16):
comm "swapper/0", pid 1, jiffies 4294667610 (age 1367.451s)
hex dump (first 16 bytes):
f0 c6 c2 bd d9 95 ff ff 00 00 00 00 00 00 00 00 ................
backtrace:
[<00000000bc81d9b1>] kmem_cache_alloc_trace+0x2f6/0x500
[<00000000d28be229>] rcu_torture_init+0x1235/0x1354
[<0000000032c3acd9>] do_one_initcall+0x51/0x210
[<000000003c117727>] kernel_init_freeable+0x205/0x259
[<000000003961f965>] kernel_init+0x1a/0x120
[<000000001998f890>] ret_from_fork+0x22/0x30
This is caused by the rcu_test_debug_objects() function allocating an
rcu_head structure, then failing to free it. This commit therefore adds
the needed kfree() after the last use of this structure.

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.
