[PATCH 6/9] btrfs: refactor the code that read from disk

This is a preparatory patch, to help the adding of the RAID 5/6 recovery code. In case of availability of all disks, this code is good for all the RAID profiles. However in case of failure, the error handling is quite different. Refactoring this code increases the general readability. Signed-off-b

[PATCH 4/9] btrfs: avoiding a rescan for a device which was already not founded.

[PATCH V4] Add support for BTRFS raid5/6 to GRUB

Hi All, the aim of this patches set is to provide support for a BTRFS raid5/6 filesystem in GRUB. The first patch, implements the basic support for raid5/6. I.e this works when all the disks are present. The next 5 patches, are preparatory ones. The 7th patch implements the raid5 recovery for

[PATCH 8/9] btrfs: make more generic the code for RAID 6 rebuilding

The original code which handles the recovery of a RAID 6 disks array assumes that all reads are multiple of 1 << GRUB_DISK_SECTOR_BITS and it assumes that all the I/O is done via the struct grub_diskfilter_segment. This is not true for the btrfs code. In order to reuse the native grub_raid6_recover

[PATCH 2/9] btrfs: add helper to check the btrfs header.

This helper will be used in few places to help the debugging. As conservative approach, in case of error it is only logged. This because I am not sure if this can change something in the error handling of the currently existing code. Signed-off-by: Goffredo Baroncelli --- grub-core/fs/btrfs.c |

[PATCH 5/9] btrfs: move logging code in grub_btrfs_read_logical()

A portion of the logging code is moved outside a for(;;). The part that is left inside is the one which depends by the for(;;) index. This is a preparatory patch: in the next one it will be possible to refactor the code inside the for(;;) in an another function. --- grub-core/fs/btrfs.c | 25 +
