6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aleksa Sarai <cyphar@xxxxxxxxxx>
[ Upstream commit 6a64c5220c5df235448b846aeff3c0660d4cc83e ]
If you pass an fd using FSCONFIG_SET_FD, autofs_parse_fd() "steals" the
param->file and so the fs_context infrastructure will not do fput() for
us.
Fixes: e6ec453bd0f0 ("autofs: convert autofs to use the new mount api")
