[ Upstream commit c6cc4c5a72505a0ecefc9b413f16bec512f38078 ]
RHBZ: 1848178
Some calls that set attributes, like utimensat(), are not supposed to return
-EINTR and thus do not have handlers for this in glibc which causes us
to leak -EINTR to the applications which are also unprepared to handle it.
For example tar will break if utimensat() return -EINTR and abort unpacking
the archive. Other applications may break too.
To handle this we add checks, and retry, for -EINTR in cifs_setattr()
