The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image. Signed-off-by:

When data starts from the beginning of NAND page, 'len' must be zero, not c->wbuf_page. Thanks to Zoltan Sogor for reporting this problem. Signed-off-by:

The bit mask used for oob size calculation was using 2 bits instead of one. Fortunately the next bit has been 0 all the time. Thanks to Nathan H. for pointing this out Signed-off-by: -

While this might be useful for all supported flash types, it is mandatory for proper JFFS2 support with Sibley flash. Signed-off-by:

This updates the Primary Vendor-Specific Extended Query parsing to version 1.4 in order to get the information about the Configurable Programming Mode regions implemented in the Sibley flash, as well as selecting the appropriate write command code. This flash does not behave like traditional NOR flash when writing data. While mtdblock should just work, further changes are needed for JFFS2 use. Signed-off-by:

When JFFS22 is unable to read the root inode, the bad root inode object is not freed and remains sticked in the jffs2_i slab cache. When we further try to free the slab cache (e.g., on rmmod jffs2), slab allocator subsystem panics. Fix this bug. Signed-off-by:

JFFS2 uses f->dents to store the pointer to the symlink target string (in case the inode is symlink). This is somewhat ugly to use the same field for different reasons. Introduce distinct field f->target for this purpose. Note, f->fragtree, f->dents, f->target may probably be put in a union. Signed-off-by:
