| |
Hi,
since mmap() allocates space in units of pages, are the bytes after the end of the file to the end of the page initialized to 0? Are the bytes after the last page initialized 0?
I installed the e2compress-patch (http://netspace.net.au/~reiter/e2compr.html) and noticed, that the bytes after the fileend just contain garbage.
If this is not the right behavior, is it save to modify the new readpage() routine (as replacement for generic_readpage() ) to initialize the whole page with 0, before actually reading the page, or will this have any bad sideefects ?
TIA,
Lars
