In the upstream kernel the FALLOC_FL_PUNCH_HOLE #define was introduced after the fallocate() function was moved from the inode_operations to the file_operations structure. Therefore, the SPL code assumed that if FALLOC_FL_PUNCH_HOLE was defined it was safe to use f_ops->fallocate(). Unfortunately, the RHEL6.4 kernel has only backported the FALLOC_FL_PUNCH_HOLE #define and not the fallocate() change. To address this compatibility issue the spl_filp_fallocate() helper function was added to properly detect which interface is available. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> |
