From: Shakeel Butt <shakeelb@xxxxxxxxxx>
Subject: vfs: remove might_sleep() from clear_inode()
7994e6f72543 ("vfs: Move waiting for inode writeback from end_writeback()
to evict_inode()") removed inode_sync_wait() from end_writeback() and
commit dbd5768f87ff ("vfs: Rename end_writeback() to clear_inode()")
renamed end_writeback() to clear_inode(). After these patches there is no
sleeping operation in clear_inode(). So, remove might_sleep() from it.
