Changes: == 1. Merge xfs_find_desired_extent() and xfs_seek_data_hole() into xfs_seek_extent(), and place it at xfs_file.c. 2. Using t; /archives/xfs/2011-11/msg00459.html (14,169 bytes)

Do you plan on updating Josef's old xfstests support patch for SEEK_DATA/SEEK_HOLE? Also i; /archives/xfs/2011-11/msg00493.html (14,014 bytes)
