2005-08-19[PATCH] jffs2: fix symlink error handlingAl Viro
The current calling conventions for ->follow_link() are already fairly complex. What we have is 1) you can return -error; then you must release nameidata yourself and ->put_link() will _not_ be called. 2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0 3) you can do nd_set_link(nd, path) and return 0 4) you can return 0 (after having moved nameidata yourself) jffs2 follow_link() is broken - it has an exit where it returns -EIO and leaks nameidata.

2005-05-23[JFFS2] Use a single config option for write buffer supportAndrew Victor
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.

2005-05-23[JFFS2] Add support for JFFS2-on-Dataflash devices.Andrew Victor
For Dataflash, can_mark_obsolete = false and the NAND write buffering code (wbuf.c) is used. Since the DataFlash chip will automatically erase pages when writing, the cleanmarkers are not needed - so cleanmarker_oob = false and cleanmarker_size = 0 DataFlash page-sizes are not a power of two (they're multiples of 528 bytes). The SECTOR_ADDR macro (added in the previous core patch) is replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is selected.

2005-05-23[JFFS2] Core changes required to support JFFS2-on-Dataflash devices.Andrew Victor
DataFlash page-sizes are not a power of two (they're multiples of 528 bytes). There are a few places in JFFS2 code where sector_size is used as a bitmask. A new macro (SECTOR_ADDR) was defined to calculate these sector addresses. For non-DataFlash devices, the original (faster) bitmask operation is still used. In scan.c, the EMPTY_SCAN_SIZE was a constant of 1024. Since this could be larger than the sector size of the DataFlash, this is now basically set to MIN(sector_size, 1024). Addition of a jffs2_is_writebuffered() macro. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
