2015-02-10xfs: only trace buffer items if they existDave Chinner1-2/+3
The commit 2d3d0c5 ("xfs: lobotomise xfs_trans_read_buf_map()") left a landmine in the tracing code: trace_xfs_trans_buf_read() is now call on all buffers that are read through this interface rather than just buffers in transactions. For buffers outside transaction context, bp->b_fspriv is null, and so the buf log item tracing functions cannot be called. This causes a NULL pointer dereference in the trace_xfs_trans_buf_read() function when tracing is turned on. cc: <stable@vger.kernel.org> Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>

2015-02-06xfs: report proper f_files in statfs if we overshoot imaxpctEric Sandeen1-0/+5
Normally, a statfs syscall reports m_maxicount as f_files (total file nodes in file system) because it is supposed to be the upper limit for dynamically-allocated inodes. It's possible, however, to overshoot imaxpct / m_maxicount. If this happens, we should report the actual number of allocated inodes, which is contained in sb_icount. Add one more adjustment to the statfs code to make this happen.

Conflicts: drivers/net/vxlan.c drivers/vhost/net.c include/linux/if_vlan.h net/core/dev.c The net/core/dev.c conflict was the overlap of one commit marking an existing function static whilst another was adding a new function. In the include/linux/if_vlan.h case, the type used for a local variable was changed in 'net', whereas the function got rewritten to fix a stacked vlan bug in 'net-next'. In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next' overlapped with an endainness fix for VHOST 1.0 in 'net'. In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter in 'net-next' whereas in 'net' there was a bug fix to pass in the correct network namespace pointer in calls to this function.

2015-02-05nilfs2: fix deadlock of segment constructor over I_SYNC flagRyusuke Konishi3-7/+44
Nilfs2 eventually hangs in a stress test with fsstress program. This issue was caused by the following deadlock over I_SYNC flag between nilfs_segctor_thread() and writeback_sb_inodes(): nilfs_segctor_thread() nilfs_segctor_thread_construct() nilfs_segctor_unlock() nilfs_dispose_list() iput() iput_final() evict() inode_wait_for_writeback() * wait for I_SYNC flag writeback_sb_inodes() * set I_SYNC flag on inode->i_state __writeback_single_inode() do_writepages() nilfs_writepages() nilfs_construct_dsync_segment() nilfs_segctor_sync() * wait for completion of segment constructor inode_sync_complete() * clear I_SYNC flag after __writeback_single_inode() completed writeback_sb_inodes() calls do_writepages() for dirty inodes after setting I_SYNC flag on inode->i_state. do_writepages() in turn calls nilfs_writepages(), which can run segment constructor and wait for its completion. On the other hand, segment constructor calls iput(), which can call evict() and wait for the I_SYNC flag on inode_wait_for_writeback(). Since segment constructor doesn't know when I_SYNC will be set, it cannot know whether iput() will block or not unless inode->i_nlink has a non-zero count. We can prevent evict() from being called in iput() by implementing sop->drop_inode(), but it's not preferable to leave inodes with i_nlink == 0 for long periods because it even defers file truncation and inode deallocation. So, this instead resolves the deadlock by calling iput() asynchronously with a workqueue for inodes with i_nlink == 0.

2015-02-04NFSv4.1: Ask for no delegation on OPEN if using O_DIRECTTrond Myklebust2-26/+83
If we're using NFSv4.1, then we have the ability to let the server know whether or not we believe that returning a delegation as part of our OPEN request would be useful. The feature needs to be used with care, since the client sending the request doesn't necessarily know how other clients are using that file, and how they may be affected by the delegation. For this reason, our initial use of the feature will be to let the server know when the client believes that handing out a delegation would not be useful. The first application for this function is when opening the file using O_DIRECT. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
