Hi Amon,

i've added your patch:
# strings /lib/libc-2.11.3.so |grep -i syncfs
syncfs

But configure of ceph still claims there is no syncfs support.

# ./configure |grep -i sync
checking for syncfs... no
checking for sync_file_range... yes

Any ideas?

Hint: I'm compiling my packages on an OpenVZ RHEL6 based virtual 
container - so THIS kernel where i'm compiling does not support syncfs 
is this the reason?

Stefan
