# grep 1488035935.129:282 /var/log/audit/audit.log |audit2why 
type=AVC msg=audit(1488035935.129:282): avc:  denied  { getattr } for
pid=3662 comm="git-daemon" path="/review/review.gluster.org/git"
dev="vdb1" ino=8388690
scontext=system_u:system_r:git_system_t:s0-s0:c0.c1023
tcontext=unconfined_u:object_r:git_user_content_t:s0 tclass=dir

	Was caused by:
	The boolean git_system_enable_homedirs was set incorrectly. 
	Description:
	Allow git to system enable homedirs

	Allow access by executing:
	# setsebool -P git_system_enable_homedirs 1

So I just enabled the right boolean, I will defer the proper fix for
later (ie, use a different label for the git repository)
