Zhihao Cheng f7e252d7e4 ubifs: Rectify space amount budget for mkdir/tmpfile operations ... [ Upstream commit a6dab6607d ] UBIFS should make sure the flash has enough space to store dirty (Data that is newer than disk) data (in memory), space budget is exactly designed to do that. If space budget calculates less data than we need, 'make_reservation()' will do more work(return -ENOSPC if no free space lelf, sometimes we can see "cannot reserve xxx bytes in jhead xxx, error -28" in ubifs error messages) with ubifs inodes locked, which may effect other syscalls. A simple way to decide how much space do we need when make a budget: See how much space is needed by 'make_reservation()' in ubifs_jnl_xxx() function according to corresponding operation. It's better to report ENOSPC in ubifs_budget_space(), as early as we can.
