Subject: [GIT PULL] Smack additional patch for v5.11

Hello Linus

Sorry for the 2nd pull request, but this is a fairly important fix
for the privilege handling of smackfs in the face of io_uring. The
novel use of kernel threads in io_uring invalidated an long standing
assumption regarding the privilege of kernel threads. The fix is
simple and safe. It was provided by Jens Axboe <>
and has been tested.

The following changes since commit 9b0072e2b2b588ad75c94f2c6e6c52c8f4bd2657:

  security/smack: remove unused varible 'rc' (2020-11-16 17:26:31 -0800)

are available in the Git repository at: smack-for-5.11
