[Minios-devel] [UNIKRAFT PATCH v5 0/2] introduce vfscore

[Yuri Volchkov <yuri.volchkov@xxxxxxxxx>]

The series provides an initial implementation of the vfs abstraction layer.

Changes since v1:
1) Fix a silly mistake at blocking access to std(in|out|err) files -
   the check have to be "fd < 2", not "fd <= 2"
2) Add fops for std(out|err). This makes it a series, not just a single patch

Changes since v2:
1) Fix compiler warrning about droping 'const'
2) Export get_file() - needed for functions like accept()

Changes since v3:
1) Protect file descriptors bitmap with crytical section
2) Use coutk() functions for both stderr and stdout
3) fix copy-paste mistakes

Changes since v4:
1) get_file return -ENFILE on error
