This patch should fix following issue: BUG: sleeping function called from invalid context at include/linux/buffer_head.h:349 in_atomic(): 1, irqs_disabled(): 0, pid: 137, name: kworker/u128:1 5 locks held by kworker/u128:1/137: #0: ("writeback"){......}, at: [<ffffffff81085618>] process_one_work+0x228/0x4d0 #1: ((&(&wb->dwork)->work)){......}, at: [<ffffffff81085618>] process_one_work+0x228/0x4d0 #2: (jbd2_handle){......}, at: [<ffffffff81242622>] start_this_handle+0x712/0x7b0 #3: (&ei->i_data_sem){......}, at: [<ffffffff811fa387>] ext4_map_blocks+0x297/0x430 #4: (&(&bgl->locks[i].lock)->rlock){......}, at: [<ffffffff811f3180>] ext4_read_block_bitmap_nowait+0x5d0/0x630 CPU: 3 PID: 137 Comm: kworker/u128:1 Not tainted 3.17.0-rc2-00184-g82752e4 #165 Hardware name: Intel Corporation W2600CR/W2600CR, BIOS SE5C600.86B.99.99.x028.061320111235 06/13/2011 Workqueue: writeback bdi_writeback_workfn (flush-1:0) 0000000000000411 ffff880813777288 ffffffff815c7fdc ffff880813777288 ffff880813a8bba0 ffff8808137772a8 ffffffff8108fb30 ffff880803e01e38 ffff880803e01e38 ffff8808137772c8 ffffffff811a8d53 ffff88080ecc6000 Call Trace: [<ffffffff815c7fdc>] dump_stack+0x51/0x6d [<ffffffff8108fb30>] __might_sleep+0xf0/0x100 [<ffffffff811a8d53>] __sync_dirty_buffer+0x43/0xe0 [<ffffffff811a8e03>] sync_dirty_buffer+0x13/0x20 [<ffffffff8120f581>] ext4_commit_super+0x1d1/0x230 [<ffffffff8120fa03>] save_error_info+0x23/0x30 [<ffffffff8120fd06>] __ext4_error+0xb6/0xd0 [<ffffffff8120f260>] ? ext4_group_desc_csum+0x140/0x190 [<ffffffff811f2d8c>] ext4_read_block_bitmap_nowait+0x1dc/0x630 [<ffffffff8122e23a>] ext4_mb_init_cache+0x21a/0x8f0 [<ffffffff8113ae95>] ? lru_cache_add+0x55/0x60 [<ffffffff8112e16c>] ? add_to_page_cache_lru+0x6c/0x80 [<ffffffff8122eaa0>] ext4_mb_init_group+0x190/0x280 [<ffffffff8122ec51>] ext4_mb_good_group+0xc1/0x190 [<ffffffff8123309a>] ext4_mb_regular_allocator+0x17a/0x410 [<ffffffff8122c821>] ? ext4_mb_use_preallocated+0x31/0x380 [<ffffffff81233535>] ? ext4_mb_new_blocks+0x205/0x8e0 [<ffffffff8116ed5c>] ? kmem_cache_alloc+0xfc/0x180 [<ffffffff812335b0>] ext4_mb_new_blocks+0x280/0x8e0 [<ffffffff8116f2c4>] ? __kmalloc+0x144/0x1c0 [<ffffffff81221797>] ? ext4_find_extent+0x97/0x320 [<ffffffff812257f4>] ext4_ext_map_blocks+0xbc4/0x1050 [<ffffffff811fa387>] ? ext4_map_blocks+0x297/0x430 [<ffffffff811fa3ab>] ext4_map_blocks+0x2bb/0x430 [<ffffffff81200e43>] ? ext4_init_io_end+0x23/0x50 [<ffffffff811feb44>] ext4_writepages+0x564/0xaf0 [<ffffffff815cde3b>] ? _raw_spin_unlock+0x2b/0x40 [<ffffffff810ac7bd>] ? lock_release_non_nested+0x2fd/0x3c0 [<ffffffff811a009e>] ? writeback_sb_inodes+0x10e/0x490 [<ffffffff811a009e>] ? writeback_sb_inodes+0x10e/0x490 [<ffffffff811377e3>] do_writepages+0x23/0x40 [<ffffffff8119c8ce>] __writeback_single_inode+0x9e/0x280 [<ffffffff811a026b>] writeback_sb_inodes+0x2db/0x490 [<ffffffff811a0664>] wb_writeback+0x174/0x2d0 [<ffffffff810ac359>] ? lock_release_holdtime+0x29/0x190 [<ffffffff811a0863>] wb_do_writeback+0xa3/0x200 [<ffffffff811a0a40>] bdi_writeback_workfn+0x80/0x230 [<ffffffff81085618>] ? process_one_work+0x228/0x4d0 [<ffffffff810856cd>] process_one_work+0x2dd/0x4d0 [<ffffffff81085618>] ? process_one_work+0x228/0x4d0 [<ffffffff81085c1d>] worker_thread+0x35d/0x460 [<ffffffff810858c0>] ? process_one_work+0x4d0/0x4d0 [<ffffffff810858c0>] ? process_one_work+0x4d0/0x4d0 [<ffffffff8108a885>] kthread+0xf5/0x100 [<ffffffff810990e5>] ? local_clock+0x25/0x30 [<ffffffff8108a790>] ? __init_kthread_worker+0x70/0x70 [<ffffffff815ce2ac>] ret_from_fork+0x7c/0xb0 [<ffffffff8108a790>] ? __init_kthread_work Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org |
