From 5c5c5e51b26413d50a9efae2ca7d6c5c6cd453ac Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Wed, 30 Apr 2008 00:54:43 -0700 Subject: fuse: update file size on short read If the READ request returned a short count, then either - cached size is incorrect - filesystem is buggy, as short reads are only allowed on EOF So assume that the size is wrong and refresh it, so that cached read() doesn't zero fill the missing chunk.
