jffs2: Use pr_fmt and remove jffs: from formats

2012-03-26T23:40:19+00:00

Use pr_fmt to prefix KBUILD_MODNAME to appropriate logging messages. Remove now unnecessary internal prefixes from formats. Signed-off-by: Joe Perches Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

jffs2: Dynamically choose inocache hash size

2010-10-24T23:57:19+00:00

When JFFS2 is used for large volumes, the mount times are quite long. Increasing the hash size provides a significant speed boost on the OLPC XO-1 laptop. Add logic that dynamically selects a hash size based on the size of the medium. A 64mb medium will result in a hash size of 128, and a 512mb medium will result in a hash size of 1024.

[JFFS2] Track parent inode for directories (for NFS export)

2008-05-01T17:47:17+00:00

To support NFS export, we need to know the parent inode of directories. Rather than growing the jffs2_inode_cache structure, share space with the nlink field -- which was always set to 1 for directories anyway. Signed-off-by: David Woodhouse

[JFFS2] Add erase_checking_list to hold blocks being marked.

2008-04-23T13:15:24+00:00

Just to keep the debug code happy when it's adding all the blocks up. Otherwise, they disappear for a while while the locks are dropped to check them and write the cleanmarker. Signed-off-by: David Woodhouse

[JFFS2] Relax threshold for triggering GC due to dirty blocks.

2007-10-13T10:29:07+00:00

Instead of matching resv_blocks_gcmerge, which is only about 3, instead match resv_blocks_gctrigger, which includes a proportion of the total device size. These ought to become tunable from userspace, at some point. Signed-off-by: David Woodhouse

[JFFS2] Trigger garbage collection when very_dirty_list size becomes excessive

2007-10-06T19:12:58+00:00

With huge amounts of free space, we weren't bothering to GC for while a while, and pathological numbers of obsolete nodes were accumulating, seriously affecting performance on NAND flash (OLPC trac #3978) Signed-off-by: David Woodhouse

[JFFS2] Tidy up licensing/copyright boilerplate.

2007-04-25T13:16:47+00:00

In particular, remove the bit in the LICENCE file about contacting Red Hat for alternative arrangements. Their errant IS department broke that arrangement a long time ago -- the policy of collecting copyright assignments from contributors came to an end when the plug was pulled on the servers hosting the project, without notice or reason. We do still dual-license it for use with eCos, with the GPL+exception licence approved by the FSF as being GPL-compatible. It's just that nobody has the right to license it differently.

JFFS2: memory leak in jffs2_do_mount_fs()

2007-02-09T15:00:21+00:00

If jffs2_sum_init() fails, c->blocks is not freed neither in jffs2_do_mount_fs() nor in jffs2_do_fill_super(). Signed-off-by: Dmitry Adamushko Signed-off-by: David Woodhouse
