2005-11-29	[JFFS2] Fix the slab cache constructor of 'struct jffs2_inode_info' objects.	Thomas Gleixner	1	-1/+1
	JFFS2 initialize f->sem mutex as "locked" in the slab constructor which is a bug. Objects are freed with unlocked f->sem mutex. So, when they allocated again, f->sem is unlocked because the slab cache constructor is not called for them. The constructor is called only once when memory pages are allocated for objects (namely, when the slab layer allocates new slabs). So, sometimes 'struct jffs2_inode_info' are allocated with unlocked f->sem, sometimes with locked. This is a bug. Instead, initialize f->sem as unlocked in the constructor. I.e., in the "constructed" state f->sem must be unlocked. From: Keijiro Yano <keijiro_yano@yahoo.co.jp> Acked-by: Artem B.

2005-11-06	[JFFS2] Add erase block summary support (mount time improvement)	Ferenc Havasi	1	-1/+7
	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.

2005-11-06	[JFFS2] Remove support for virtual blocks	Ferenc Havasi	1	-2/+2
	Remove support for virtual blocks, which are build by concatenation of multiple physical erase blocks. For more information please read the MTD mailing list thread "[PATCH] remove support for virtual blocks" Signed-off-by: Ferenc Havasi <havasi@inf.u-szeged.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2005-07-13	[JFFS2] Init locks early during mount	Artem B. Bityuckiy	1	-1/+10
	In case of a mount error locks might be uninitialized but accessed by the resulting call to jffs2_kill_sb(). Signed-off-by: Artem B. Bityuckiy <dedekind@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23	[JFFS2] Use a single config option for write buffer support	Andrew Victor	1	-2/+2
	This patch replaces the current CONFIG_JFFS2_FS_NAND, CONFIG_JFFS2_FS_NOR_ECC and CONFIG_JFFS2_FS_DATAFLASH with a single configuration option - CONFIG_JFFS2_FS_WRITEBUFFER. The only functional change of this patch is that the slower div/mod calculations for SECTOR_ADDR(), PAGE_DIV() and PAGE_MOD() are now always used when CONFIG_JFFS2_FS_WRITEBUFFER is enabled.

2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+365
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
