94b7cc3711 Fix a few problems in fopen and freopen
fopen should set the FD_CLOEXEC flag if requested evenif the kernel does
not support an aotmic operation.

freopen should reuse the file descriptor for the stream.  This is
especially important for calls to change the standard streams (stin,
stdout, stderr).

5bd6dc5c2c Use prlimit64 for 32-bit [gs]etrlimit64 implementation. 2010-12-25 20:12:27 -05:00
3cdaa6adb1 f_flags in Linux statfs implementation.
The 2.6.36 kernel provides an additional field in the statfs results.
Use this value in the statvfs emulation to avoid filling in f_flag
the hard way.

81c84bd902 Fix F_GETOWN on some Linux archs.
The syscall conventions on some Linux archs prevented F_GETOWN from working
correctly in some situations.  This can be rectified when using the new
F_GETOWN_EX command.
