  "message": "kernfs: invoke kernfs_unmap_bin_file() directly from kernfs_deactivate()\n\nkernfs_unmap_bin_file() is supposed to unmap all memory mappings of\nthe target file before kernfs_remove() finishes; however, it currently\nis being called from kernfs_addrm_finish() and has the same race\nproblem as the original implementation of deactivation when there are\nmultiple removers - only the remover which snatches the node to its\naddrm_cxt-\u003eremoved list is guaranteed to wait for its completion\nbefore returning.\n\nIt can be easily fixed by moving kernfs_unmap_bin_file() invocation\nfrom kernfs_addrm_finish() to kernfs_deactivated().  The function may\nbe called multiple times but that shouldn\u0027t do any harm.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
