[Minios-devel] [UNIKRAFT PATCH v3 0/4] Changes for supporting Python 2

[Costin Lupu <costin.lupu@xxxxxxxxx>]

These changes are needed for some of the Python 2 unit tests. Some tests may
use a large number of files, therefore we had to increase our limit. Other
files try to close the standard file descriptors (0-2), therefore the VM
shouldn't crash if such behavior is wanted. Also, some unit tests need
recursive mutexes.

Changes since v1:
- Applied comments
- Added 'lib/vfscore: sys_ioctl() - Handle FIOCLEX and FIONCLEX requests' patch

Changes since v2:
- Fixed UK_MUTEX_INITIALIZER()

Costin Lupu (4):
  lib/vfscore: Use a scalable bitmap for open file descriptors
  lib/vfscore: Return error when trying to close standard file
    descriptors
  lib/vfscore: sys_ioctl() - Handle FIOCLEX and FIONCLEX requests
  lib/uklock: Make mutex recursive
