| * net: avoid synchronize_rcu() in dev_deactivate_manyEric Dumazet2011-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_deactivate_many() issues one synchronize_rcu() call after qdiscs set to noop_qdisc. This call is here to make sure they are no outstanding qdisc-less dev_queue_xmit calls before returning to caller. But in dismantle phase, we dont have to wait, because we wont activate again the device, and we are going to wait one rcu grace period later in rollback_registered_many(). After this patch, device dismantle uses one synchronize_net() and one rcu_barrier() call only, so we have a ~30% speedup and a smaller RTNL latency.

| * net: remove synchronize_net() from netdev_set_master()Eric Dumazet2011-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the old days, we used to access dev->master in __netif_receive_skb() in a rcu_read_lock section. So one synchronize_net() call was needed in netdev_set_master() to make sure another cpu could not use old master while/after we release it. We now use netdev_rx_handler infrastructure and added one synchronize_net() call in bond_release()/bond_release_all() Remove the obsolete synchronize_net() from netdev_set_master() and add one in bridge del_nbp() after its netdev_rx_handler_unregister() call. This makes enslave -d a bit faster. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Jiri Pirko <jpirko@redhat.com> CC: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | V3: rename NETDEV_ENSLAVE to NETDEV_JOIN Currently we do nothing when we enslave a net device which is running netconsole. Neil pointed out that we may get weird results in such case, so let's disable netpoll on the device being enslaved. I think it is too harsh to prevent the device being ensalved if it is running netconsole. By the way, this patch also removes the NETDEV_GOING_DOWN from netconsole netdev notifier, because netpoll will check if the device is running or not and we don't handle NETDEV_PRE_UP neither.

This allows us to remove the compat_do_execve() code from fs/compat.c and reimplement compat_do_execve() as the trivial wrapper on top of do_execve_common(is_compat => true). In fact, this fixes another (minor) bug. "compat_uptr_t str" can overflow after "str += len" in compat_copy_strings() if a 64bit application execs via sys32_execve(). Unexport acct_arg_size() and get_arg_page(), fs/compat.c doesn't need them any longer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ail flush code has always relied upon log flushing to prevent it from spinning needlessly. This fixes it to wait on the last I/O request submitted (we don't need to wait for all of it) instead of either spinning with io_schedule or sleeping. As a result cpu usage of gfs2_logd is much reduced with certain workloads.

The first part deallocates any directory leaf blocks and marks the directory as being a regular file when that is complete. The second stage was identical to deallocating regular files. Regular files have their data blocks in a different address space to directories, and thus what would have been normal data blocks in a regular file (the hash table in a GFS2 directory) were deallocated correctly. However, a reference to these blocks was left in the journal (assuming of course that some previous activity had resulted in those blocks being in the journal or ail list). This patch uses the i_depth as a test of whether the inode is an exhash directory (we cannot test the inode type as that has already been changed to a regular file at this stage in deallocation) The original issue was reported by Chris Hertel as an issue he encountered running bonnie++ Reported-by: Christopher R.

It would be nice to just define a variable to reuse. For example I may have: TEST_START [...] TEST = ssh root@mybox /path/to/my/script TEST_START [...] TEST = ssh root@mybox /path/to/my/script [etc] The issue is, I may wont to change that script or one of the other fields. Then I need to update each line individually. With the addition of config variables (variables only used during parsing the config) we can simplify the config files. These variables can also be defined multiple times and each time the new value will overwrite the old value. The convention to use a config variable over a ktest option is to use := instead of =. Now we could do: USER := root TARGET := mybox TEST_SCRIPT := /path/to/my/script TEST_CASE := ${USER}@${TARGET} ${TEST_SCRIPT} TEST_START [...] TEST = ${TEST_CASE} TEST_START [...] TEST = ${TEST_CASE} [etc] Now we just need to update the variables at the top.

| * | | | | nilfs2: use mark_buffer_dirty to mark btnode or meta data dirtyRyusuke Konishi2011-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces nilfs_mdt_mark_buffer_dirty and nilfs_btnode_mark_dirty macros with mark_buffer_dirty and gets rid of nilfs_mark_buffer_dirty, an own mark buffer dirty function.

| * | | | | nilfs2: always set back pointer to host inode in mapping->hostRyusuke Konishi2011-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current nilfs, page cache for btree nodes and meta data files do not set a valid back pointer to the host inode in mapping->host. This will change it so that every address space in nilfs uses mapping->host to hold its host inode. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
| * | | | | nilfs2: get rid of NILFS_I_NILFSRyusuke Konishi2011-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces all references of NILFS_I_NILFS(inode)->ns_bdev with inode->i_sb->s_bdev and unfolds remaining uses of NILFS_I_NILFS inline function. Before 2.6.37, referring to a nilfs object from inodes needed a conditional judgement, and NILFS_I_NILFS was helpful to simplify it. But now we can simply do it by going through a super block instance like inode->i_sb->s_fs_info. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses list_first_entry macro instead of list_entry if it's used to get the first entry. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
