Subject: fuse2fs: don't update atime when reading executable file content
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2d211fdd8866fbd1b085f0628ce9dac9a4a80c10;p=thirdparty%2Fe2fsprogs.git

fuse2fs: don't update atime when reading executable file content

The kernel doesn't update the atime of program files when it's paging
their content into memory, so fuse2fs shouldn't either.  Found by
generic/120.
