. add all sys/sys headers not already present to help compiling . take netbsd dirent.h and struct dirent; main result is introducing d_type and d_namlen that have to be set by getdents() in all FS code implementing it . d_off is gone . alignment of the struct has become 8 bytes instead of 4 . remove _MAX_BLOCK_SIZE, _MIN_BLOCK_SIZE, _STATIC_BLOCK_SIZE . libminlib: cleanup unused yet duplicate code . mfs: throw out the long-broken v1, v2 support . new test for dirent contents filled by getdents() Change-Id: I1459755c7ba5e5d1c9396d3a587ce6e63ddc283e
