The log "posix set mdata failed, No ctime" logged repeatedly
after the fix [1]. Those could be internal fops. This patch
fixes the same.

posix/ctime: Fix stat(time attributes) inconsistency during readdirp

2019-04-16T10:57:12+00:00

Problem:
   Creation of tar file on gluster volume throws warning
'file changed as we read it'

Cause:
   During readdirp, for few of the files whose inode is not
present, time attributes were served from backend. This caused
the ctime of few files to be different between before readdir
and after readdir by tar.

Solution:
  If ctime feature is enabled and inode is not present, don't
serve the time attributes from backend file, serve it from xattr.

core: brick process is crashed at the time of spawn thread

2019-01-11T06:02:52+00:00

Problem: brick is getting crashed at the time of calling
         pthread_detach after just call gf_thread_create.If
         sufficient resources are not available on the system
         pthread_create returns EAGAIN (non-negative) but the
         caller function expects negative error code in case of failure

Solution: Change the condition in caller function to avoid the crash
