Subject: [PATCH 0/5] i_size/i_disksize update fixes and cleanup series

#First two patches are simply cleanups
use ext4_update_i_disksize instead of opencoded ones
move i_size, i_diskzie update routines to helper function
# Simple fix found during code review
ext4_zero_range fix incorect journal credits reservation
# Fixes i_size,i_disksize,mtime,ctime update issues
# primary test: xfstest generic/019
fix transaction issues for fallocate and zero_range
update sync i_disksize coherently with block allocation

In fact last two issues can be fixed by inserting inode to orphan list
during file grow, but this turns to be a problem for ext4_writepages because
orhpan list is protected by i_mutex.

BTW: May be it is reasonable serialize orhpan list manipulations by i_data_sem?
