avoid all reclaimable inodes in xfs_sync_inodes_ag If we are syncing data in xfs_sync_inodes_ag(), the VFS inode must still be referencable as the dirty data state is carried on the VFS inode. hence if we can't get a reference via igrab(), the inode must be in reclaim which implies that it has no dirty data attached. Leave such inodes to the reclaim code to flush the dirty inode state to disk and so avoid attempting to access the VFS inode when it may not exist in xfs_sync_inodes_ag(). Version 4: o don't reference liinux inode untiil after igrab() succeeds Version 3: o converted unlock/rele to an xfs_iput() call. Version 2: o change igrab logic to be more linear o remove initial reclaimable inode check now that we are using igrab() failure to find reclaimable inodes o assert that igrab failure occurs only on reclaimable inodes o clean up inode locking - only grab the iolock if we are doing a SYNC_DELWRI call and we have a dirty inode.

Prevent looping in xfs_sync_inodes_ag If the last block of the AG has inodes in it and the AG is an exactly power-of-2 size then the last inode in the AG points to the last block in the AG. If we try to find the next inode in the AG by adding one to the inode number, we increment the inode number past the size of the AG. The result is that the macro XFS_INO_TO_AGINO() will strip the AG portion of the inode number and return an inode number of zero. That is, instead of terminating the lookup loop because we hit the inode number went outside the valid range for the AG, the search index returns to zero and we start traversing the radix tree from the start again. This results in an endless loop in xfs_sync_inodes_ag(). Fix it be detecting if the new search index decreases as a result of incrementing the current inode number. That indicate an overflow and hence that we have finished processing the AG so we can terminate the loop.

Kill SYNC_CLOSE SYNC_CLOSE is only ever used and checked in conjunction with SYNC_WAIT, and this only done in one spot. The only thing this does is make XFS_bflush() calls to the data buftargs. This will happen very shortly afterwards the xfs_sync() call anyway in the unmount path via the xfs_close_devices(), so this code is redundant and can be removed. That only user of SYNC_CLOSE is now gone, so kill the flag completely. Signed-off-by: Dave Chinner <david@fromorbit.com> Merge of xfs-linux-melb:xfs-kern:32310a by kenmcd. Kill SYNC_CLOSE
