However, if lock_mount() doesn\u0027t transit, we\u0027re then\nleft with an extra ref on the mountpoint vfsmount which needs releasing.\nWe can handle that in follow_managed() by not making assumptions about what\nwe can and what we cannot get from lookup_mnt() as the current code does.\n\nThe callers of follow_managed() expect that reference to path-\u003emnt will be\ngrabbed iff path-\u003emnt has been changed. follow_managed() and follow_automount()\nkeep track of whether such reference has been grabbed and assume that it\u0027ll\nhappen in those and only those cases that\u0027ll have us return with changed\npath-\u003emnt. That assumption is almost correct - it breaks in case of\nracing automounts and in even harder to hit race between following a mountpoint\nand a couple of mount --move. The thing is, we don\u0027t need to make that\nassumption at all - after the end of loop in follow_manage() we can check\nif path-\u003emnt has ended up unchanged and do mntput() if needed.\n\nThe BUG can be reproduced with the following test program:\n\n\t#include \u003cstdio.h\u003e\n\t#include \u003csys/types.h\u003e\n\t#include \u003csys/stat.h\u003e\n\t#include \u003cunistd.h\u003e\n\t#include \u003csys/wait.h\u003e\n\tint main(int argc, char **argv)\n\t{\n\t\tint pid, ws;\n\t\tstruct stat buf;\n\t\tpid \u003d fork();\n\t\tstat(argv[1], \u0026buf);\n\t\tif (pid \u003e 0) wait(\u0026ws);\n\t\treturn 0;\n\t}\n\nand the following procedure:\n\n (1) Mount an NFS volume that on the server has something else mounted on a\n subdirectory. For instance, I can mount / from my server:\n\n\tmount warthog:/ /mnt -t nfs4 -r\n\n On the server /data has another filesystem mounted on it, so NFS will see\n a change in FSID as it walks down the path, and will mark /mnt/data as\n being a mountpoint. This will cause the automount code to be triggered.\n\n !!! Do not look inside the mounted fs at this point !!!\n\n (2) Run the above program on a file within the submount to generate two\n simultaneous automount requests:\n\n\t/tmp/forkstat /mnt/data/testfile\n\n (3) Unmount the automounted submount:\n\n\tumount /mnt/data\n\n (4) Unmount the original mount:\n\n\tumount /mnt\n\n At this point the kernel should throw a BUG with something like the\n following:\n\n\tBUG: Dentry ffff880032e3c5c0{i\u003d2,n\u003d} still in use (1) [unmount of nfs4 0:12]\n\nNote that the bug appears on the root dentry of the original mount, not the\nmountpoint and not the submount because sys_umount() hasn\u0027t got to its final\nmntput_no_expire() yet, but this isn\u0027t so obvious from the call trace:\n\n [\u003cffffffff8117cd82\u003e] shrink_dcache_for_umount+0x69/0x82\n [\u003cffffffff8116160e\u003e] generic_shutdown_super+0x37/0x15b\n [\u003cffffffffa00fae56\u003e] ? nfs_super_return_all_delegations+0x2e/0x1b1 [nfs]\n [\u003cffffffff811617f3\u003e] kill_anon_super+0x1d/0x7e\n [\u003cffffffffa00d0be1\u003e] nfs4_kill_super+0x60/0xb6 [nfs]\n [\u003cffffffff81161c17\u003e] deactivate_locked_super+0x34/0x83\n [\u003cffffffff811629ff\u003e] deactivate_super+0x6f/0x7b\n [\u003cffffffff81186261\u003e] mntput_no_expire+0x18d/0x199\n [\u003cffffffff811862a8\u003e] mntput+0x3b/0x44\n [\u003cffffffff81186d87\u003e] release_mounts+0xa2/0xbf\n [\u003cffffffff811876af\u003e] sys_umount+0x47a/0x4ba\n [\u003cffffffff8109e1ca\u003e] ? trace_hardirqs_on_caller+0x1fd/0x22f\n [\u003cffffffff816ea86b\u003e] system_call_fastpath+0x16/0x1b\n\nas do_umount() is inlined.

That way we don\u0027t have to remove journal_head\nexplicitely via jbd2_journal_remove_journal_head() and instead just\nremove journal_head when b_jcount drops to zero. The result of this is\nthat [__]jbd2_journal_refile_buffer(),\n[__]jbd2_journal_unfile_buffer(), and\n__jdb2_journal_remove_checkpoint() can free journal_head which needs\nmodification of a few callers. Also we have to be careful because once\njournal_head is removed, buffer_head might be freed as well.
