fs: btrfs: use fs_ls_generic() and drop custom implementation

2026-07-10T21:55:01Z

Now that generic callbacks for opendir/readdir/closedir are implemented, the custom btrfs_ls() implementation is no longer needed, along with the btrfs_iter_dir() callback iterator. Use fs_ls_generic() instead. Signed-off-by: Alexey Charkov Reviewed-by: Qu Wenruo

fs: btrfs: hide duplicate 'Cannot lookup file' error on 'load'

2024-11-15T19:11:47Z

Running commands such as 'load mmc 2:1 $addr $path' when path does not exists will print an error twice if the file does not exist, e.g.: ``` Cannot lookup file boot/boot.scr Failed to load 'boot/boot.scr' ``` (where the first line is printed by btrfs and the second by common fs code) Historically other filesystems such as ext4 or fat have not been printing a message here, so do the same here to avoid duplicate. The other error messages in this function are also somewhat redundant, but bring useful diagnostics if they happen somewhere, so have been left as printf. Note that if a user wants no message to be printed for optional file loads, they have to check for file existence first with other commands such as 'size'.

fs: btrfs: fix reading when length specified

2023-11-16T23:59:58Z

The btrfs read function limits the read length to ensure that it and the read offset do not together exceed the size of the file. However, this size was only being queried if the read length was passed a value of zero (meaning "whole file"), and the size is defaulted to 0 otherwise. This means the clamp will just zero out the length if one is specified, preventing reading of the file. Fix this by checking the file size unconditionally, and unifying the default length and clamping logic as a single range check instead. This bug was discovered when trying to boot Linux with initrd= via 'bootefi' from a btrfs partition. The EFI stub entered an infinite loop of zero-length reads while trying to read the initrd, and the boot process stalled indefinitely. Signed-off-by: Sam Edwards Reviewed-by: Qu Wenruo

fs: btrfs: change directory list output to be aligned as before

Since commit 325dd1f642dd ("fs: btrfs: Use btrfs_iter_dir() to ...") when btrfs is listing a directory, the output is not aligned: 15 Wed Sep 09 13:20:03 2020 boot.scr -> @/boot/boot.scr 0 Tue Feb 02 12:42:09 2021 @ 108 Tue Feb 02 12:54:04 2021 1.info Return back to how it was displayed previously, i.e.: 15 Wed Sep 09 13:20:03 2020 boot.scr -> @/boot/boot.scr 0 Tue Feb 02 12:42:09 2021 @ < > 108 Tue Feb 02 12:54:04 2021 1.info Instead of '', print '< >', as ext4 driver.
