JFFS2: retry large buffer allocations

2011-05-25T01:00:50+00:00

Replace direct call to kmalloc for a potentially large, contiguous
buffer allocation with one to mtd_kmalloc_up_to which helps ensure the
operation can succeed under low-memory, highly- fragmented situations
albeit somewhat more slowly.

jffs2: Reduce excessive scan of empty blocks

2010-10-25T00:12:20+00:00

Scanning 1024 bytes to see if an EB is empty is a bit much.
Lower it to 256 bytes and make sure the while loop is
optimized.

jffs2: Use jffs2_garbage_collect_trigger() to trigger pending erases

2010-05-19T16:10:44+00:00

This is now done in a GC pass; we don't need to trigger kupdated to do it.

[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.

[JFFS2] Handle dirents on the flash with embedded zero bytes in names.

2007-10-13T10:35:58+00:00

In three places: summary scan, normal scan, REF_PRISTINE GC.

Just truncate at the NUL, since that was the correct thing to do in the
only case where this (inexplicable) breakage has been seen.

2007-09-23T17:41:17+00:00

Fix a couple of instances in JFFS2 where the unpoint() routine is
being called with the wrong length in cases where the point() routine
truncated a request.
