unfortunately, just checking MS_BORN after having grabbed ->s_umount in sget() is not enough; places that pick superblock from a list and grab s_umount shared need the same check in addition to checking for ->s_root; otherwise three-way race between failing mount, sget() and such list-walker can leave us with list-walker coming *second*, when temporary active ref grabbed by sget() (to be dropped when sget() notices that original mount has failed by checking MS_BORN) has lead to deactivate_locked_super() from failing ->mount() *not* doing ->kill_sb() and just releasing ->s_umount. Once sget() gets through and notices that MS_BORN had never been set it will drop the active ref and fs will be shut down and kicked out of all lists, but it's too late for something like sync_supers().

Seeing that just about every destructor got that INIT_LIST_HEAD() copied into it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once(); the cost of taking it into inode_init_always() will be negligible for pipes and sockets and negative for everything else. Not to mention the removal of boilerplate code from ->destroy_inode() instances... Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

tomoyo/realpath.c needs exactly one include - that of common.h. It pulls everything the thing needs, without doing ridiculous garbage such as trying to include ../../fs/internal.h. If that alone doesn't scream "layering violation", I don't know what does; and these days it's all for nothing, since it fortunately does not use any symbols defined in there...

a) mount --move is checking that ->mnt_parent is non-NULL before looking if that parent happens to be shared; ->mnt_parent is never NULL and it's not even an misspelled !mnt_has_parent() b) pivot_root open-codes is_path_reachable(), poorly. c) so does path_is_under(), while we are at it.

vfsmounts have ->mnt_parent pointing either to a different vfsmount or to itself; it's never NULL and termination condition in loops traversing the tree towards root is mnt == mnt->mnt_parent. At least one place (see the next patch) is confused about what's going on; let's add an explicit helper checking it right way and use it in all places where we need it. Not that there had been too many, but... Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

This reverts commit c0afabd3. It causes failures on Toshiba laptops - instead of disabling the alarm, it actually seems to enable it on the affected laptops, resulting in (for example) the laptop powering on automatically five minutes after shutdown. There's a patch for it that appears to work for at least some people, but it's too late to play around with this, so revert for now and try again in the next merge window.

Commit 1e39f384 ("evm: fix build problems") makes the stub version of security_old_inode_init_security() return 0 when CONFIG_SECURITY is not set. But that makes callers such as reiserfs_security_init() assume that security_old_inode_init_security() has set name, value, and len arguments properly - but security_old_inode_init_security() left them uninitialized which then results in interesting failures. Revert security_old_inode_init_security() to the old behavior of returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this just fine. [ Also fixed the S_PRIVATE(inode) case of the actual non-stub security_old_inode_init_security() function to return EOPNOTSUPP for the same reason, as pointed out by Mimi Zohar. It got incorrectly changed to match the new function in commit fb88c2b6: "evm: fix security/security_old_init_security return code". - Linus ] Reported-by: NJorge Bastos <mysql.jorge@decimal.pt> Acked-by: NJames Morris <jmorris@namei.org> Acked-by: NMimi Zohar <zohar@us.ibm.com> Signed-off-by: NJan Kara <jack@suse.cz> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
