NAME fallocate - preallocate or deallocate space to a file SYNOPSIS fallocate [-c|-p|-z] [-o offset] -l length [-n] filename fallocate -d [-o offset] [-l length] filename DESCRIPTION fallocate is used to manipulate the allocated disk space for a file, either to deallocate or preallocate it. For filesystems which support the fallocate system call, preallocation is done quickly by allocating blocks and marking them as uninitialized, requiring no IO to the data blocks. This is much faster than creating a file by filling it with zeroes. function old new delta fallocate_main - 179 +179 applet_names 2597 2606 +9 applet_main 1504 1508 +4 applet_suid 94 95 +1 applet_install_loc 188 189 +1 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
