fs/ext2: Add BR2_TARGET_ROOTFS_EXT2_MKFS_OPTIONS option

2017-07-09T13:35:42+00:00

This option lets the user specify mke2fs options and/or ext2/3/4 features. Signed-off-by: Sébastien Szymanski Signed-off-by: Samuel Martin Cc: "Yann E.

fs/ext2: rename BR2_TARGET_ROOTFS_EXT2_BLOCKS to BR2_TARGET_ROOTFS_EXT2_SIZE

2017-07-09T13:35:30+00:00

This change deprecates the ext2/3/4 rootfs size in blocks symbol in favor of one that mimic the fs-size argument behavior of mkfs (i.e. size in a human readable format accepting k, m, g or t suffix or their upper-case variants). This change also updates the defconfigs that used to set BR2_TARGET_ROOTFS_EXT2_BLOCKS symbol.

fs/ext2: use mkfs to generate rootfs image

2017-07-04T22:39:38+00:00

mkfs is now capable of generating rootfs images. Use mkfs instead of genext2fs. If not set, we now let mkfs calculate the block size and the number of inodes needed. This change also adjusts the options to meet those of mkfs. Notes: * Passing a null inode number to mkfs triggers its automatic calculation. * Passing a fs-size with no unit suffix to mkfs is interpreted as using 1K block size.

fs/ext2: deprecate BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option

2017-07-04T22:35:00+00:00

Soon, the ext{2,3,4} rootfs image will no longer be generated with genext2fs, but using mke2fs instead which has no support for the extra inode number option. So, deprecate the BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option and recommend, in lieu, to set the total inode number, taking account of the extra ones if needed.

fs/ext2: allow reserving zero block for root

2017-07-04T06:47:57+00:00

The previous default, zero, just meant "use the default value of the filesystem generator", which happened to be 5% (the traditional value for all ext-creating tools we've ever seen). So, change the new default accordingly to 5%. Signed-off-by: "Yann E. MORIN" Signed-off-by: Samuel Martin Signed-off-by: Thomas Petazzoni

fs/ext2: Remove support for auto-calculation of rootfs size

2017-03-25T13:41:05+00:00

Auto-calculation of the rootfs size cannot be done in a reliable way as it depends on the host filesystem and is broken on non ext4 host (see bugs [1] [2]). So let the user specify the size he wants for his rootfs.

fs/ext2: default to ext2 rev1

2016-12-14T14:59:38+00:00

Rev0 is very old (E.G. from before Linux was maintained in git), the kernel prints a scary warning when used: EXT4-fs warning (device sda): ext4_update_dynamic_rev:746: updating to rev 1 because of new feature flag, running e2fsck is recommended And rev0 support is broken in u-boot 2016.11: http://lists.denx.de/pipermail/u-boot/2016-December/275916.html So default to rev1 instead.
