Hi all,
with this patch series I try to clean the vmtruncate code. The theory of
operation:
old new
vmtruncate() => inode_newsize_ok+truncate_setsize+fs truncate
Where vmtruncate was used without any error check, the code now is:
if (inode_newsize_ok() == 0) {
truncate_setsize();
fs truncate();
}
So, performance and semantic nothing change at all. I think that maybe
in some point we can skip inode_newsize_ok (where the error check of
vmtruncate wasn't used) but since there is a swap check in case of
no-extension, maybe it's better to avoid regressions. After this clean,
of course, each fs can clean in a deeply way.
With these patches even the inode truncate callback is deleted.
Any comments/feedback/bugs are welcome.
