From 716ea734e4cd83a2030ca2cac10056bdaab1a021 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Fri, 17 Dec 2010 23:08:01 -0800 Subject: Rename vfs operation posix_fallocate to just fallocate and add the vfs_fallocate_mode parameter. It turns out we need the fallocate operations to be able to both allocate and extend filesize, and to allocate and not extend filesize, and posix_fallocate can only do the former. So by defining the vfs op as posix_fallocate we lose the opportunity to use any underlying syscalls (like Linux fallocate) that can do the latter as well. We don't currently use the non-extending filesize call, but now I've changed the vfs op definition we can in the future. For the moment simply map the fallocate op onto posix_fallocate for the VFS_FALLOCATE_EXTEND_SIZE case and return ENOSYS for the VFS_FALLOCATE_KEEP_SIZE case. Jeremy.
