- The primary reason is that mkfs and installboot need to run natively during
the cross compilation (host and target versions are compiled). There is a
collision of include files though. E.g. a.out.h is very minix-specific.
Therefore some files we moved and replaced by stubs that include the original
file if compiling on or for Minix :
include/a.out.h -> include/minix/a.out.h
include/sys/dir.h -> include/minix/dir.h
include/dirent.h -> include/minix/dirent.h
include/sys/types.h -> include/minix/types.h
- This does not break any native compilation on Minix. Other headers that were
including the original files are changed according to include directly the
new, minix specific location not to pick up the host system includes while
cross-compiling.
- role of this patch is to make rebasing of the build branch simpler until the
new build system is merged
Implemented by changing write_map to accept a WMAP_FREE flag. In that
case, it doesn't update the datablock (creating indirect zones as
necessary) pointer, but it frees the datablock if present. Also it
frees the single and double indirect blocks if unused.
This makes the implementation of truncate_inode() simpler.
truncate_inode() now accepts a truncation length which makes
implementing truncate() and ftruncate() simple.
This also allowed implementing the F_FREESP fcntl().
