  "message": "fix open/umount race\n\nnameidata_to_filp() drops nd-\u003epath or transfers it to opened\nfile.  In the former case it\u0027s a Bad Idea(tm) to do mnt_drop_write()\non nd-\u003epath.mnt, since we might race with umount and vfsmount in\nquestion might be gone already.\n\nFix: don\u0027t drop it, then...  IOW, have nameidata_to_filp() grab nd-\u003epath\nin case it transfers it to file and do path_drop() in callers.  After\nthey are through with accessing nd-\u003epath...\n\nReported-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n",
