<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>This file system mirrors the existing file system hierarchy of the system, starting at the root file system. This is implemented by just "passing through" all requests to the corresponding user-space libc functions. In contrast to passthrough.c and passthrough_fh.c, this implementation uses the low-level API. Its performance should be the least bad among the three, but many operations are not implemented. In particular, it is not possible to remove files (or directories) because the code necessary to defer actual removal until the file is not opened anymore would make the example much more complicated.</p>
<p>When writeback caching is enabled (-o writeback mount option), it is only possible to write to files for which the mounting user has read permissions. This is because the writeback cache requires the kernel to be able to issue read requests for all files (which the passthrough filesystem cannot satisfy if it can't read the file in the underlying filesystem).</p>
<p>Compile with: </p><pre class="fragment">gcc -Wall passthrough_ll.c `pkg-config fuse3 --cflags --libs` -o passthrough_ll
