* Claim maintainership for block2mtd and update email addressesJoern Engel2008-02-06
| | | | | | | | | | | | | | I have been prime author and maintainer of block2mtd from day one, but neither MAINTAINERS nor the module source makes this fact clear. And while I'm at it, update my email addresses tree-wide, as the old address currently bounces and change my name to "joern" as unicode will likely continue to cause trouble until the end of this century.

* | mm: make read_cache_page synchronousNick Piggin2007-05-07
|/ | | | | | | | | | | | | | | | Ensure pages are uptodate after returning from read_cache_page, which allows us to cut out most of the filesystem-internal PageUptodate calls. I didn't have a great look down the call chains, but this appears to fixes 7 possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in block2mtd. All depending on whether the filler is async and/or can return with a !uptodate page.

* [PATCH] [MTD] block2mtd: remove readahead codeJoern Engel2007-02-20
| | | | | | | | | | | | | Over the years there was a slow trickle of complaints against the readahead code. Most of them concerned performance, Peter Zijlstra stumbled over it when working unrelated changes and I believe there was an actual bug report. Oh, Andrew Morton also complained about duplicating code from mm/readahead.c. It is just not worth it. On flash media like usb sticks, readahead will make things go slow - very slow. On spinning disks, readahead may be a win, but this is definitely not the place to add it. Signed-off-by: Jörn Engel <joern@lazybastard.org>

* block2mtd.c: Make kernel boot command line arguments work (try 4)Ville Herva2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Trying to pass kernel command line arguments to block2mtd at boot-time does not work currently. block2mtd_setup() is called so early that kmalloc() fails nevermind being able to do open_bdev_excl() (which requires rootfs to be mounted. This patch only saves the option string at the early boot stage, and parses them later when block2mtd_init() is called. If open_bdev_excl() fails, open_by_devnum(name_to_dev_t()) is tried instead, which makes it possible to initialize the driver before rootfs has been mounted. Also gets rid of the superfluous parse_name() that only checks if name is longer than 80 chars and copies it to a string that is not kfreed. With this patch, I can boot statically compiled block2mtd, and mount jffs2 as rootfs (without modules or initrd), with lilo config like this: root=/dev/mtdblock0 append="rootfstype=jffs2 block2mtd.block2mtd=/dev/hdc2,65536" (Note that rootfstype=jffs2 is required, since the kernel only tries filesystems without "nodev" attribute by default, and jffs is "nodev"). Compared to first version of this patch, this one does not copy the parameters to the global buffer if init has already been called, and the global array is marked as __initdata. Compared to the second version of this patch, module build is fixed. Compared to the third version of this patch, statically compiled block2mtd driver with no boot-time parameter no longer gives spurious error 'cannot open device ""' Signed-off-by: Ville Herva <vherva@vianova.fi> Acked-by: Jörn Engel <joern@wohnheim.fh-wedel.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | | | | | | | | | | | | There's a mem leak in drivers/mtd/devices/block2mtd.c::block2mtd_setup() We can leak 'name' allocated with kmalloc in 'parse_name' if leave via the 'parse_err' macro since it contains a return but doesn't do any freeing.

* mtd: improve parameter parsing for block2mtdJoern Engel2006-04-19
| | | | | | | | | | | | | | | | | | | | Expand the parameter parsing for block2mtd. It now accepts: Ki, Mi, Gi - the official prefixes for binary multiples, see http://physics.nist.gov/cuu/Units/binary.html, ki - mistake on my side and analog to "k" for decimal multiples, KiB, MiB, GiB - for people that prefer to add a "B" for byte, kiB - combination of the above. There were complaints about not accepting "k" for 1024. This has long been common practice, but is known to lead to confusion. Hence the new SI units and hence block2mtd only accepts units that cannot be confused with decimal units. Diverging from common practice doesn't always please people, even if the change is for the better.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
