* fallocate: add FALLOC_FL_ZERO_RANGE supportLukas Czerner2014-04-181-0/+14

* fallocate: introduce an option -c to support COLLAPSE_RANGEDongsu Park2014-04-181-0/+7
| | | | | | | | | | | | Introduce a new option -c (or --collapse-range) to support a new flag FALLOC_FL_COLLAPSE_RANGE for fallocate(2). It will nullify a particular range [offset, offset+len] by shifting extents beyond the range to the beginning of the hole.

The fallocate(1) utility is used to preallocate blocks to a file. This can be useful for virtual images, database files, testing, etc. Normally we'd hope that various tools will start using preallocation internally, but until then such a utility may be useful, and could be scripted as well. The original Eric's version is available at: http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/2490 This version: - checks for fallocate glibc function and kernel syscall - does not provide a fallback and does not call posix_fallocate() - adds long options - uses err.h for errro messages - adds NLS support - cleanups man page Co-Author: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>
