We update the ctime/mtime of a block device when we remove it so that blkid knows the device changed. However we do this by re-opening the block device and calling filp_update_time. This is more correct because it'll call the inode->i_op->update_time if it exists, but the block dev inodes do not do this. Instead call generic_update_time() on the bd_inode in order to avoid the blkdev_open path and get rid of the following lockdep splat: ====================================================== WARNING: possible circular locking dependency detected 5.14.0-rc2+ #406 Not tainted ------------------------------------------------------ losetup/11596 is trying to acquire lock: ffff939640d2f538 ((wq_completion)loop0){+.+.}-{0:0}, at: flush_workqueue+0x67/0x5e0 but task is already holding lock: ffff939655510c68 (&lo->lo_mutex){+.+.}-{3:3}, at: __loop_clr_fd+0x41/0x660 [loop] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #4 (&lo->lo_mutex){+.+.}-{3:3}: __mutex_lock+0x7d/0x750 lo_open+0x28/0x60 [loop] blkdev_get_whole+0x25/0xf0 blkdev_get_by_dev.part.0+0x168/0x3c0 blkdev_open+0xd2/0xe0 do_dentry_open+0x161/0x390 path_openat+0x3cc/0xa20 do_filp_open+0x96/0x120 do_sys_openat2+0x7b/0x130 __x64_sys_openat+0x46/0x70 do_syscall_64+0x38/0x90 entry_SYSCALL_64_after_hwframe+0x44/0xae -> #3 (&disk->open_mutex){+.+.}-{3:3}: __mutex_lock+0x7d/0x750 blkdev_get_by_dev.part.0+0x56/0x3c0 blkdev_open+0xd2/0xe0 do_dentry_open+0x161/0x390 path_openat+0x3cc/0xa20 do_filp_open+0x96/0x120 file_open_name+0xc7/0x170 filp_open+0x2c/0x50 btrfs_scratch_superblocks.part.0+0x10f/0x170 btrfs_rm_device.cold+0xe8/0xed btrfs_ioctl+0x2a31/0x2e70 __x64_sys_ioctl+0x80/0xb0 do_syscall_64+0x38/0x90 entry_SYSCALL_64_after_hwframe+0x44/0xae -> #2 (sb_writers#12){.+.+}-{0:0}: lo_write_bvec+0xc2/0x240 [loop] loop_process_work+0x238/0xd00 [loop] process_one_work+0x26b/0x560 worker_thread+0x55/0x3c0 kthread+0x140/0x160 ret_from_fork+0x1f/0x30 -> #1 ((work_completion)(&lo->rootcg_work)){+.+.}-{0:0}: process_one_work+0x245/0x560 worker_thread+0x55/0x3c0 kthread+0x140/0x160 ret_from_fork+0x1f/0x30 -> #0 ((wq_completion)loop0){+.+.}-{0:0}: __lock_acquire+0x10ea/0x1d90 lock_acquire+0xb5/0x2b0 flush_workqueue+0x91/0x5e0 drain_workqueue+0xa0/0x110 destroy_workqueue+0x36/0x250 __loop_clr_fd+0x9a/0x660 [loop] block_ioctl+0x3f/0x50 __x64_sys_ioctl+0x80/0xb0 do_syscall_64+0x38/0x90 entry_SYSCALL_64_after_hwframe+0x44/0xae other info that might help us debug this: Chain exists of: (wq_completion)loop0 --> &disk->open_mutex --> &lo->lo_mutex Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&lo->lo_mutex); lock(&disk->open_mutex); lock(&lo->lo_mutex); lock((wq_completion)loop0); *** DEADLOCK *** 1 lock held by losetup/11596: #0: ffff939655510c68 (&lo->lo_mutex){+.+.}-{3:3}, at: __loop_clr_fd+0x41/0x660 [loop] stack backtrace: CPU: 1 PID: 11596 Comm: losetup Not tainted 5.14.0-rc2+ #406 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.13.0-2.fc32 04/01/2014 Call Trace: dump_stack_lvl+0x57/0x72 check_noncircular+0xcf/0xf0 ? stack_trace_save+0x3b/0x50 __lock_acquire+0x10ea/0x1d90 lock_acquire+0xb5/0x2b0 ? flush_workqueue+0x67/0x5e0 ? lockdep_init_map_type+0x47/0x220 flush_workqueue+0x91/0x5e0 ? flush_workqueue+0x67/0x5e0 ? verify_cpu+0xf0/0x100 drain_workqueue+0xa0/0x110 destroy_workqueue+0x36/0x250 __loop_clr_fd+0x9a/0x660 [loop] ? blkdev_ioctl+0x8d/0x2a0 block_ioctl+0x3f/0x50 __x64_sys_ioctl+0x80/0xb0 do_syscall_64+0x38/0x90 entry_SYSCALL_64_after_hwframe+0x44/0xae Reviewed-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: Josef Bacik <josef@toxicpanda.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

Puranjay Mohan says: ==================== bpf, arm64: support for timed may_goto Changes in v2->v3: v2: https://lore.kernel.org/all/20250809204833.44803-1-puranjay@kernel.org/ - Rebased on bpf-next/master - Added Acked-by: tags from Xu and Kumar Changes in v1->v2: v1: https://lore.kernel.org/bpf/20250724125443.26182-1-puranjay@kernel.org/ - Added comment in arch_bpf_timed_may_goto() about BPF_REG_FP setup (Xu Kuohai) This set adds support for the timed may_goto instruction for the arm64. The timed may_goto instruction is implemented by the verifier by reserving 2 8byte slots in the program stack and then calling arch_bpf_timed_may_goto() in a loop with the stack offset of these two slots in BPF_REG_AX. It expects the function to put a timestamp in the first slot and the returned count in BPF_REG_AX is put into the second slot by a store instruction emitted by the verifier. arch_bpf_timed_may_goto() is special as it receives the parameter in BPF_REG_AX and is expected to return the result in BPF_REG_AX as well. It can't clobber any caller saved registers because verifier doesn't save anything before emitting the call. So, arch_bpf_timed_may_goto() is implemented in assembly so the exact registers that are stored/restored can be controlled (BPF caller saved registers here) and it also needs to take care of moving arguments and return values to and from BPF_REG_AX <-> arm64 R0. So, arch_bpf_timed_may_goto() acts as a trampoline to call bpf_check_timed_may_goto() which does the main logic of placing the timestamp and returning the count. All tests that use may_goto instruction pass after the changing some of them in patch 2 #404 stream_errors:OK [...] #406/2 stream_success/stream_cond_break:OK [...] #494/23 verifier_bpf_fastcall/may_goto_interaction_x86_64:SKIP #494/24 verifier_bpf_fastcall/may_goto_interaction_arm64:OK [...] #539/1 verifier_may_goto_1/may_goto 0:OK #539/2 verifier_may_goto_1/batch 2 of may_goto 0:OK #539/3 verifier_may_goto_1/may_goto batch with offsets 2/1/0:OK #539/4 verifier_may_goto_1/may_goto batch with offsets 2/0:OK #539 verifier_may_goto_1:OK #540/1 verifier_may_goto_2/C code with may_goto 0:OK #540 verifier_may_goto_2:OK Summary: 7/16 PASSED, 25 SKIPPED, 0 FAILED ==================== Link: https://patch.msgid.link/20250827113245.52629-1-puranjay@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>
