For unrelated reasons I've enabled kmemleak in my client's kernel. While running xfstests, I get these reports on several of the tests. I've seen them on a few recent kernels as well. They do not look related to NFS. Anyone know where I should report this? [cel@manet ~]$ cat src/xfstests/results/generic/013.kmemleak EXPERIMENTAL kmemleak reported some memory leaks! Due to the way kmemleak works, the leak might be from an earlier test, or something totally unrelated. unreferenced object 0xffff88886963c4c0 (size 168): comm "mount", pid 3471, jiffies 4296003082 (age 161.789s) hex dump (first 32 bytes): 03 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<00000000fd30522a>] kmem_cache_alloc+0xc4/0x1cb [<0000000008f8eac6>] prepare_creds+0x21/0xc7 [<000000006e9e3064>] prepare_exec_creds+0xb/0x3a [<000000001b408d7e>] __do_execve_file.isra.31+0x103/0x818 [<000000004096f0a3>] do_execve+0x25/0x29 [<0000000008a9aa1c>] __x64_sys_execve+0x26/0x2b [<00000000599d3d33>] do_syscall_64+0x5a/0x68 [<00000000005d29f3>] entry_SYSCALL_64_after_hwframe+0x49/0xbe unreferenced object 0xffff888867a4f708 (size 32): comm "mount", pid 3471, jiffies 4296003082 (age 161.789s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<000000004c53b46c>] __kmalloc+0xfc/0x14a [<000000002ff13bd8>] lsm_cred_alloc.isra.5+0x24/0x32 [<000000009eb979ec>] security_prepare_creds+0x21/0x61 [<0000000086789f15>] prepare_creds+0xb3/0xc7 [<000000006e9e3064>] prepare_exec_creds+0xb/0x3a [<000000001b408d7e>] __do_execve_file.isra.31+0x103/0x818 [<000000004096f0a3>] do_execve+0x25/0x29 [<0000000008a9aa1c>] __x64_sys_execve+0x26/0x2b [<00000000599d3d33>] do_syscall_64+0x5a/0x68 [<00000000005d29f3>] entry_SYSCALL_64_after_hwframe+0x49/0xbe [cel@manet ~]$ -- Chuck Lever
