Regressions on linux next 20200803 tag kernel. LTP syscalls test umount03 mount a path for testing and umount failed and retired for 50 times and test exit with warning and following test cases using that mount path failed.
LTP syscalls tests failed list, * umount03 * umount2_01 * umount2_02 * umount2_03 * utime06 * copy_file_range01
The reported issue has been fixed in linux next 20200817 tag by below patch.
fs: fix a struct path leak in path_umount Make sure we also put the dentry and vfsmnt in the illegal flags and !may_umount cases. Fixes: 41525f56e256 ("fs: refactor ksys_umount")
