Hi Dongsu. > As discussed in the thread "[PATCH RESEND 3/10] ext4: Add support > FALLOC_FL_COLLAPSE_RANGE for fallocate", [3] this patch to util-linux > will be useful for testing collapse-range inside xfstests. As Dave pointed, this patch is needed for fsstress not xfstests. > > [1] https://lkml.org/lkml/2014/2/18/374 > [2] https://lkml.org/lkml/2014/2/20/318 > [3] https://lkml.org/lkml/2014/2/18/83 > > @@ -51,6 +52,10 @@ > # define FALLOC_FL_PUNCH_HOLE 2 > #endif > > +#ifndef FALLOC_FL_COLLAPSE_RANGE > +# define FALLOC_FL_COLLAPSE_RANGE 8 > +#endif > + > #include "nls.h" > #include "strutils.h" > #include "c.h" > @@ -66,12 +71,13 @@ static void __attribute__((__noreturn__)) usage(FILE > *out) > fprintf(out, > _(" %s [options] <filename>\n"), program_invocation_short_name); > fputs(USAGE_OPTIONS, out); > - fputs(_(" -d, --dig-holes detect and dig holes\n"), out); > - fputs(_(" -l, --length <num> length of the (de)allocation, in bytes\n"), > out); > - fputs(_(" -n, --keep-size don't modify the length of the file\n"), > out); > - fputs(_(" -o, --offset <num> offset of the (de)allocation, in bytes\n"), > out); > - fputs(_(" -p, --punch-hole punch holes in the file\n"), out); > - fputs(_(" -v, --verbose verbose mode\n"), out); > + fputs(_(" -c, --collapse-range collapse a hole in the file\n"), out); I think that it is better to change like this => "collapse space in the file" And I add util-liunx's maintainer in this mail loop.
