From: Filipe Manana <[email protected]>
This patchset fixes a couple bugs, in the two first patches, with the tree
mod log code. The remaining patches just move all that code into a separate
file, since it's quite large and ctree.c is huge as well, and do some small
refactorings and cleanups.
One of the bugs in particular, has been hit frequently by Zygo, hitting a
BUG_ON().
Filipe Manana (9):
btrfs: fix race when cloning extent buffer during rewind of an old
root
btrfs: always pin deleted leaves when there are active tree mod log
users
btrfs: move the tree mod log code into its own file
btrfs: use booleans where appropriate for the tree mod log functions
btrfs: use a bit to track the existence of tree mod log users
btrfs: use the new bit BTRFS_FS_TREE_MOD_LOG_USERS at
btrfs_free_tree_block()
btrfs: remove unnecessary leaf check at btrfs_tree_mod_log_free_eb()
btrfs: add and use helper to get lowest sequence number for the tree
mod log
btrfs: update debug message when checking seq number of a delayed ref
