From bee6c307800bbb26ba1a855b1841c2f0c4b7622a Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Fri, 17 May 2013 15:27:34 -0400 Subject: [PATCH] fuse: update inode size and invalidate attributes on fallocate An fallocate request without FALLOC_FL_KEEP_SIZE set can extend the size of a file. Update the inode size after a successful fallocate. Also invalidate the inode attributes after a successful fallocate to ensure we pick up the latest attribute values (i.e., i_blocks).
