Subject: [PATCH] vfs: remove might_sleep() from clear_inode()

Commit 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.
