Shuxiao Zhang 8f8de8d2bf staging: android: ashmem: lseek failed due to no FMODE_LSEEK. ... commit 97fbfef6bd597888485b653175fb846c6998b60c upstream. vfs_llseek will check whether the file mode has FMODE_LSEEK, no return failure. But ashmem can be lseek, so add FMODE_LSEEK to ashmem file. Comment From Greg Hackmann: ashmem_llseek() passes the llseek() call through to the backing shmem file. 91360b02ab ("ashmem: use vfs_llseek()") changed this from directly calling the file's llseek() op into a VFS layer call. This also adds a check for the FMODE_LSEEK bit, so without that bit ashmem_llseek() now always fails with -ESPIPE.
