Subject: [PATCH AUTOSEL 6.12 28/37] fs/ocfs2: use sleeping version of __find_get_block()

From: Davidlohr Bueso <dave@...olabs.net>

[ Upstream commit a0b5ff07491010789fcb012bc8f9dad9d26f9a8b ]

This is a path that allows for blocking as it does IO. Convert
to the new nonatomic flavor to benefit from potential performance
benefits and adapt in the future vs migration such that semantics
are kept.
