Wait for the receive traffic to become idle before attempting to close or reset the adapter. To enable the processing of packets while Receive Idle, move the clearing of __VXGE_STATE_CARD_UP bit in vxge_close to after it. Also, modify the return value of the ISR when the adapter is down to IRQ_HANDLED. Otherwise there are unhandled interrupts for the device.

unix_dgram_poll() is pretty expensive to check POLLOUT status, because it has to lock the socket to get its peer, take a reference on the peer to check its receive queue status, and queue another poll_wait on peer_wait. This all can be avoided if the process calling unix_dgram_poll() is not interested in POLLOUT status. It makes unix_dgram_recvmsg() faster by not queueing irrelevant pollers in peer_wait. On a test program provided by Alan Crequy : Before: real 0m0.211s user 0m0.000s sys 0m0.208s After: real 0m0.044s user 0m0.000s sys 0m0.040s Suggested-by: NDavide Libenzi <davidel@xmailserver.org> Reported-by: NAlban Crequy <alban.crequy@collabora.co.uk> Acked-by: NDavide Libenzi <davidel@xmailserver.org> Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

Alban Crequy reported a problem with connected dgram af_unix sockets and provided a test program. epoll() would miss to send an EPOLLOUT event when a thread unqueues a packet from the other peer, making its receive queue not full. This is because unix_dgram_poll() fails to call sock_poll_wait(file, &unix_sk(other)->peer_wait, wait); if the socket is not writeable at the time epoll_ctl(ADD) is called. We must call sock_poll_wait(), regardless of 'writable' status, so that epoll can be notified later of states changes.

While tracking dev_base_lock users, I found decnet used it in dnet_select_source(), but for a wrong purpose: Writers only hold RTNL, not dev_base_lock, so readers must use RCU if they cannot use RTNL.

Commit 5c521830 (ext4: Support discard requests when running in no-journal mode) attempts to add sb_issue_discard() for data blocks (in data=writeback mode) and in no-journal mode. Unfortunately, this no longer works, because in commit dd3932ed (block: remove BLKDEV_IFL_WAIT), sb_issue_discard() only presents a synchronous interface, and there are times when we call ext4_free_blocks() when we are are holding a spinlock, or are otherwise in an atomic context. For now, I've removed the call to sb_issue_discard() to prevent a deadlock or (if spinlock debugging is enabled) failures like this: BUG: scheduling while atomic: rc.sysinit/1376/0x00000002 Pid: 1376, comm: rc.sysinit Not tainted 2.6.36-ARCH #1 Call Trace: [<ffffffff810397ce>] __schedule_bug+0x5e/0x70 [<ffffffff81403110>] schedule+0x950/0xa70 [<ffffffff81060bad>] ? insert_work+0x7d/0x90 [<ffffffff81060fbd>] ? queue_work_on+0x1d/0x30 [<ffffffff81061127>] ? queue_work+0x37/0x60 [<ffffffff8140377d>] schedule_timeout+0x21d/0x360 [<ffffffff812031c3>] ? generic_make_request+0x2c3/0x540 [<ffffffff81402680>] wait_for_common+0xc0/0x150 [<ffffffff81041490>] ? default_wake_function+0x0/0x10 [<ffffffff812034bc>] ? submit_bio+0x7c/0x100 [<ffffffff810680a0>] ? wake_bit_function+0x0/0x40 [<ffffffff814027b8>] wait_for_completion+0x18/0x20 [<ffffffff8120a969>] blkdev_issue_discard+0x1b9/0x210 [<ffffffff811ba03e>] ext4_free_blocks+0x68e/0xb60 [<ffffffff811b1650>] ? __ext4_handle_dirty_metadata+0x110/0x120 [<ffffffff811b098c>] ext4_ext_truncate+0x8cc/0xa70 [<ffffffff810d713e>] ? pagevec_lookup+0x1e/0x30 [<ffffffff81191618>] ext4_truncate+0x178/0x5d0 [<ffffffff810eacbb>] ? unmap_mapping_range+0xab/0x280 [<ffffffff810d8976>] vmtruncate+0x56/0x70 [<ffffffff811925cb>] ext4_setattr+0x14b/0x460 [<ffffffff811319e4>] notify_change+0x194/0x380 [<ffffffff81117f80>] do_truncate+0x60/0x90 [<ffffffff811e08fa>] ? security_inode_permission+0x1a/0x20 [<ffffffff811eaec1>] ? tomoyo_path_truncate+0x11/0x20 [<ffffffff81127539>] do_last+0x5d9/0x770 [<ffffffff811278bd>] do_filp_open+0x1ed/0x680 [<ffffffff8140644f>] ? page_fault+0x1f/0x30 [<ffffffff81132bfc>] ? alloc_fd+0xec/0x140 [<ffffffff81118db1>] do_sys_open+0x61/0x120 [<ffffffff81118e8b>] sys_open+0x1b/0x20 [<ffffffff81002e6b>] system_call_fastpath+0x16/0x1b https://bugzilla.kernel.org/show_bug.cgi?id=22302Reported-by: NMathias Burén <mathias.buren@gmail.com> Signed-off-by: N"Theodore Ts'o" <tytso@mit.edu> Cc: jiayingz@google.com
