ext4: assign get_fs()->dev_desc before using it

2013-05-24T14:04:23Z

Commit 50ce4c0 "fs/ext4: Support device block sizes != 512 bytes" modified ext4fs_set_blk_dev() to calculate total_sect based on get_fs()->dev_desc->log2blksz rather than SECTOR_SIZE. However, this value wasn't yet assigned. Move the assignment earlier so the code doesn't crash or hang. Cc: Egbert Eich Tested-by: Tom Rini Signed-off-by: Stephen Warren

fs/ext4: Support device block sizes != 512 bytes

2013-05-10T12:16:33Z

The 512 byte block size was hard coded in the ext4 file systems. Large harddisks today support bigger block sizes typically 4096 bytes. This patch removes this limitation. Signed-off-by: Egbert Eich

Consolidate bool type

2013-04-01T20:33:52Z

'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun

fs: Move ls and read methods into ext4, fat

2013-03-04T19:19:56Z

It doesn't make a lot of sense to have these methods in fs.c. They are filesystem-specific, not generic code. Add each to the relevant filesystem and remove the associated #ifdefs in fs.c. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

ext4: Split write support into its own file

2013-03-04T19:19:56Z

This code seems to be entirely othogonal, so remove the #ifdef and put the condition in the Makefile instead. Signed-off-by: Simon Glass

fs:ext4:write: Initialize cache aligned filename buffer

2012-12-07T15:47:53Z

The filename buffer is allocated dynamically. It must be cache aligned. Moreover, it is necessary to erase its content before we use it for file name operations. This prevents from corruption of written file names. Signed-off-by: Lukasz Majewski Signed-off-by: Kyungmin Park

fs:ext4:fix: Code refactoring to suppress compiler warnings

2012-12-07T15:47:53Z

Several fixes to suppress compiler's (eldk-5.[12].x gcc 4.6) warning [-Wunused-but-set-variable] Signed-off-by: Lukasz Majewski Signed-off-by: Kyungmin Park

fs:ext4:write: Store block device descriptor in file system structure

2012-12-07T15:47:52Z

The device block descriptor (block_dev_desc_t) )shall be stored at ext4 early code (at ext4fs_set_blk_dev in this case) to be available for latter use (like put_ext4()). Signed-off-by: Lukasz Majewski Signed-off-by: Kyungmin Park

fs:ext4:write: Add lldiv and do_div to perform 64-32 bits division

2012-12-07T15:47:52Z

The ext4write code has been using direct calls to 64-32 division (/ and %). Officially supported u-boot toolchains (eldk-5.[12].x) generate calls to __aeabi_uldivmod(), which is niether defined in the toolchain libs nor u-boot source tree. Due to that, when the ext4write command has been executed, "undefined instruction" execption was generated (since the __aeabi_uldivmod() is not provided). To fix this error, lldiv() for division and do_div() for modulo have been used. Those two functions are recommended for performing 64-32 bit number division in u-boot.

fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}

2012-10-29T21:21:19Z

This makes the FAT and ext4 filesystem implementations build if CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the filesystems to be built separately from the filesystem-specific commands that use them. This paves the way for the creation of filesystem-generic commands that used the filesystems, without requiring the filesystem- specific commands. Minor documentation changes are made for this change. The new config options are automatically selected by the old config options to retain backwards-compatibility.
