Chao YuandGreg Kroah-Hartman 295b50e95e f2fs: fix to shrink read extent node in batches ...

[ Upstream commit 3fc5d5a182 ]

We use rwlock to protect core structure data of extent tree during
its shrink, however, if there is a huge number of extent nodes in
extent tree, during shrink of extent tree, it may hold rwlock for
a very long time, which may trigger kernel hang issue.

This patch fixes to shrink read extent node in batches, so that,
critical region of the rwlock can be shrunk to avoid its extreme
long time hold.
