--- Comment #27 from nh2 <nh2-redhatbugzilla at deditus.de> ---
Hey, just wanted to let you know that this bug seems not fixed with
glusterfs-3.12.4.

I still get getdents() calls returning only ~20 entries:

getdents(3, /* 20 entries */, 131072)   = 1040
getdents(3, /* 20 entries */, 131072)   = 1040
getdents(3, /* 20 entries */, 131072)   = 1040
getdents(3, /* 6 entries */, 131072)    = 312
getdents(3, /* 0 entries */, 131072)    = 0

The patch above also speaks of reduced CPU usage which I haven't tested yet.

I haven't tested with my kernel patch yet that allows FUSE readdir() to use
more than 1 page, will retest with that.
