kernel_sendpage() does the proper default case handling for when the socket doesn't have a native sendpage implementation. Now, arguably this might be something that we could instead solve by just specifying that all protocols should do it themselves at the protocol level, but we really only care about the common protocols. Does anybody really care about sendpage on something like Appletalk? Not likely. Acked-by: NDavid S.

* 'for-linus' of git://git.kernel.dk/linux-2.6-block: Remove double removal of blktrace directory
-
由 Alan D. Brunelle 提交于
commit fd51d251 Author: Stefan Raspl <raspl@linux.vnet.ibm.com> Date: Tue May 19 09:59:08 2009 +0200 blktrace: remove debugfs entries on bad path added in an explicit invocation of debugfs_remove for bt->dir, in blk_remove_buf_file_callback we are also getting the directory removed. On occasion I am seeing memory corruption that I have bisected down to this commit. [The testing involves a (long) series of I/O benchmarks with blktrace invoked around the actual runs.] I believe that this committed patch is correct, but the problem actually lies in the code in blk_remove_buf_file_callback. With this patch I am able to consistently get complete runs whereas previously I could not get a single run to complete. The first part of the patch simply moves the debugfs_remove below the relay_close: the relay_close call will remove files under bt->dir, and so we should not remove the directory until all the files we created have been removed. (Note: This is not sufficient to fix the problem - the file system code has ref counts on the directoy, so our invocation does not cause the directory to actually be removed. Nonetheless, we should not rely upon that feature.) Signed-off-by: NAlan D. Brunelle <alan.brunelle@hp.com> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

We can't call nfs_readdata_release()/nfs_writedata_release() without first initialising and referencing args.context. Doing so inside nfs_direct_read_schedule_segment()/nfs_direct_write_schedule_segment() causes an Oops. We should rather be calling nfs_readdata_free()/nfs_writedata_free() in those cases. Looking at the O_DIRECT code, the "struct nfs_direct_req" is already referencing the nfs_open_context for us. Since the readdata and writedata structures carry a reference to that, we can simplify things by getting rid of the extra nfs_open_context references, so that we can replace all instances of nfs_readdata_release()/nfs_writedata_release().

Some gigabytes have on-board SIMG5723s connected to JMB ahcis. These are used to implement hardware raid. Unfortunately some firmware revisions on these 5723s don't bring the link down when all the downstream ports are unoccupied while not responding to reset protocol which makes libata think that there's device attached to the port but is not responding and retry. This results in painfully wrong boot detection time for these ports when they're empty. This patch quirks those boards such that ahci gives up after the initial timeout. Combined with parallel probing, this gives quick enough probing and also is safe because SIMG5723 will respond to the first try if any of the downstream ports is occupied.

xfs_buf_associate_memory is used for setting up the spare buffer for the log wrap case in xlog_sync which can happen under i_lock when called from xfs_fsync. The i_lock mutex is taken in reclaim context so all allocations under it must avoid recursions into the filesystem. There are a couple more uses of xfs_buf_associate_memory in the log recovery code that are also affected by this, but I'd rather keep the code simple than passing on a gfp_mask argument. Longer term we should just stop requiring the memoery allocation in xlog_sync by some smaller rework of the buffer layer. Reported by the new reclaim context tracing in lockdep.

Between GCC version 3.4.0 and 4.3.3 (including 3.4.0 and 4.3.3), -mtune=merced is implemented in GCC. Starting from 4.4.0, -mtune=merced is deprecated. Even implemented in versions between 3.4.0 and 4.3.3, the -mtune=merced feature has been broken in some of the versions. For example, GCC 4.1.2 reports interanl tuning function errors during kernel building with -mtune=merced. Or GCC Bugzilla 16130 reports another -mtune=merced issue on GCC 3.4.1. So I would remove the -mtune=merced from IA64 kernel build. Without this option, kernel on Merced will remain the same except losing an unstable and out-of-date performance tunning feature. Since GCC version 3.4.0, -mtune=mckinley has been implemented. The -mtune=mckinley option functions the same as mtune=itanium2. And mtune=itanium2 is the default option. So we don't need to add mtune=mckinley either since its been the default option in any GCC version which implements this option. Signed-off-by: NFenghua Yu <fenghua.yu@intel.com>
