2007-03-09[JFFS2] Check for all-zero node headersDavid Woodhouse
Due to a poor choice of CRC32 seed, a node header which is all zeroes would pass the CRC32 check. Explicitly check for this case, and treat it as we do a CRC failure. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2007-03-08[JFFS2] Use yield() between GC passes in background thread.David Woodhouse
The garbage collection thread is strictly an optimisation. Everything it does would also be done just-in-time in the context of something in userspace trying to access the file system. Sometimes, however, it's a pessimisation. Especially during early boot when it's checksumming nodes and scanning inodes which are shortly going to be pulled in by read_inode anyway. We end up building the rbtree of node coverage twice for the same inode. By switching to yield() instead of cond_resched() in the main loop, we observe boot times on the OLPC system going down from about 100 seconds to 60.

2007-03-08[JFFS2] Fix writebuffer recovery in the first page of a blockVitaly Wool
For the case when nand_write_page fail with -EIO for the first page in an eraseblock, jffs2_wbuf_recover ends up producing a BUG in jffs2_block_refile as jeb->first_node is not yet set up (it's set up later in jffs2_wbuf_recover). This BUG is not really a bug; it's just jffs2_wbuf_recover calling jffs2_block_refile with the wrong second parameter. This patch takes care of this situation.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-09[JFFS2] Use MTD_OOB_AUTO to automatically place cleanmarker on NANDArtem Bityutskiy
Nowadays MTD supports an MTD_OOB_AUTO option which allows users to access free bytes in NAND's OOB as a contiguous buffer, although it may be highly discontinuous. This patch teaches JFFS2 to use this nice feature instead of the old MTD_OOB_PLACE option. This for example caused problems with OneNAND. Now JFFS2 does not care how are the free bytes situated. This may change position of the clean marker on some flashes, but this is not a problem. JFFS2 will just re-erase the empty eraseblocks and write the new (correct) clean marker.

2006-11-28[MTD] [NAND] remove len/ooblen confusion.Vitaly Wool
As was discussed between Ricard Wanderlöf, David Woodhouse, Artem Bityutskiy and me, the current API for reading/writing OOB is confusing. The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account.

2006-10-01[PATCH] Streamline generic_file_* interfaces and filemap cleanupsBadari Pulavarty
This patch cleans up generic_file_*_read/write() interfaces. Christoph Hellwig gave me the idea for this clean ups. In a nutshell, all filesystems should set .aio_read/.aio_write methods and use do_sync_read/ do_sync_write() as their .read/.write methods. This allows us to cleanup all variants of generic_file_* routines.
