While testing a linux 5.2 kernel I noticed it fails to mount my glusterfs volumes.<br>
<br>
It repeatedly fails with:<br>
[2019-06-11 09:15:27.106946] W [fuse-bridge.c:4993:fuse_thread_proc] 0-glusterfs-fuse: read from /dev/fuse returned -1 (Invalid argument)<br>
[2019-06-11 09:15:27.106955] W [fuse-bridge.c:4993:fuse_thread_proc] 0-glusterfs-fuse: read from /dev/fuse returned -1 (Invalid argument)<br>
[2019-06-11 09:15:27.106963] W [fuse-bridge.c:4993:fuse_thread_proc] 0-glusterfs-fuse: read from /dev/fuse returned -1 (Invalid argument)<br>
[2019-06-11 09:15:27.106971] W [fuse-bridge.c:4993:fuse_thread_proc] 0-glusterfs-fuse: read from /dev/fuse returned -1 (Invalid argument)<br>
etc. <br>
etc.<br>
<br>
Bisecting turned up as culprit:<br>
commit d4b13963f217dd947da5c0cabd1569e914d21699: fuse: require /dev/fuse reads to have enough buffer capacity<br>
<br>
The glusterfs version i'm using is from Debian stable:<br>
ii glusterfs-client 3.8.8-1 amd64 clustered file-system (client package)<br>
ii glusterfs-common 3.8.8-1 amd64 GlusterFS common libraries and translator modules<br>
<br>
<br>
A 5.1.* kernel works fine, as does a 5.2-rc4 kernel with said commit reverted.<br>
