It is fine if there is not free space - we should still allow mounting this FS. This patch relaxes the free space requirements and adds info dumps. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

UBIFS does not disable compression if ui->flags is non-zero, e.g. if the file has "sync" flag. This is because of the typo which is fixed by this patch. The patch also adds a couple of useful debugging prints. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

These are mostly long lines and wrong indentation warning fixes. But also there are two volatile variables and checkpatch.pl complains about them: WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gc_seq; WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gced_lnum; Well, we anyway use smp_wmb() for c->gc_seq and c->gced_lnum, so these 'volatile' modifiers can be just dropped.

The 'make_free_space()' function was too complex and this patch simplifies it. It also fixes a bug - the freespace test failed straight away on UBI volumes with 512 bytes LEB size. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

Do not force UBIFS return 0 used space when it is empty. It leads to a situation when creating any file immediately produces tens of used blocks, which looks very weird. It is better to be honest and say that some blocks are used even if the FS is empty. And ext2 does the same. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

UBIFS stores uncommitted index size in c->budg_uncommitted_idx, and this affect budgeting calculations. When mounting and replaying, this variable is not updated, so we may end up with "over-budgeting". This patch fixes the issue. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

UBIFS commits on unmount to make the next mount faster. Currently, it commits only if there is more than LEB size bytes in the journal. This is not very good, because journal size may be large (512KiB). And there may be few deletions in the journal which do not take much journal space, but which do introduce a lot of TNC changes and make mount slow. Thus, jurt remove this condition and always commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

UBI now has (fake for now, though) synchronization call - use it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
-
Artem Bityutskiy authored
Always run commit in sync_fs, because even if the journal seems to be almost empty, there may be a deletion which removes a large file, which affects the index greatly. And because we want better free space predictions after 'sync_fs()', we have to commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

Argh. The ->sync_fs call is called _before_ all inodes are flushed. This means we first sync write buffers and commit, then all inodes are synced, and we end up with unflushed write buffers! Fix this by forcing synching all indoes from 'ubifs_sync_fs()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

The c->min_idx_lebs constant depends on c->old_idx_sz, which is read from the master node. This means that we have to initialize c->min_idx_lebs only after we have read the master node. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

Do not calculate min_idx_lebs, because it is available in c->min_idx_lebs Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

When we commit, but before we try to write anything to the flash media, @c->min_idx_size is inaccurate, because we do not re-calculate it after the commit. Do not forget to do this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

Take into account that 2 eraseblocks are never available because they are reserved for the index. This gives more realistic count of FS blocks. To avoid future confusions like this, introduce a constant. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

If data does not compress, it is better to leave it uncompressed because we'll read it faster then. So do not compress data if we save less than 64 bytes. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

This fixes the MN10300 kernel module linking to match the toolchain. RELA relocs don't use the value at the location being relocated. This has been working because the tools always leave the value at the target location cleared.
