2011-05-13UBIFS: introduce a separate structure for budgeting infoArtem Bityutskiy
This patch separates out all the budgeting-related information from 'struct ubifs_info' to 'struct ubifs_budg_info'. This way the code looks a bit cleaner. However, the main driver for this is that we want to save budgeting information and print it later, so a separate data structure for this is helpful. This patch is a preparation for the further debugging output improvements. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-03-08UBIFS: improve find function interfaceArtem Bityutskiy
Make 'ubifs_find_free_space()' return offset where free space starts, rather than the amount of free space. This is just more appropriat for its caller. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-09-30UBIFS: remove unneeded unlikely()Hirofumi Nakagawa
IS_ERR() macro already has unlikely(), so do not use constructions like 'if (unlikely(IS_ERR())'. Signed-off-by: Hirofumi Nakagawa <hnakagawa@miraclelinux.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-09-17UBIFS: remove incorrect assertAdrian Hunter
The assert was not valid because one of the variables 'taken_empty_lebs' has transient values out of sync with the other variables. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-08-31UBIFS: add forgotten gc_idx_lebs componentArtem Bityutskiy
We add this component at other similar places, but not in this one. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-08-31UBIFS: fix assertionArtem Bityutskiy
The assertion was incorrect, because it did not take into account free space. This patch also amends the comments correspondingly, and cleans them up a little. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-08-13UBIFS: reserve more space for indexArtem Bityutskiy
At the moment UBIFS reserves twice old index size space for the index. But this is not enough in some cases, because if the indexing node are very fragmented and there are many small gaps, while the dirty index has big znodes - in-the-gaps method would fail. Thus, reserve trise as more, in which case we are guaranteed that we can commit in any case. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
