[U-Boot] [Regression][ext4] Regression at EXT4 filesystem code

[Lukasz Majewski]

Dear All,

In the newest master u-boot 
(SHA1: 1674df60d17e0e72396c961d5390bb62b184ad95)

I've found a regression with writing to EXT4 file system:

Writing uImage to ext4 partition - created with Debian's
mkfs.ext4 /dev/sdd2 (size 58M)

dfu-util -R -a2 -D arch/arm/boot/uImage
uImage size - 4.8 MiB

GADGET DRIVER: usb_dnl_dfu
USB PHY0 Enable

The old file is still present on the partition.


After reverting following patch:

Commit: "ext4fs: Add ext4 extent cache for read operations"
SHA1: fc0fc50f38a4d7d0554558076a79dfe8b0d78cd5

I am able to store files on the ext4 partition:	

USB PHY0 Enable
#File System is consistent
file found deleting
update journal finished

Any ideas how to fix it?
