X-Git-Tag: v4.16-rc1~49^2~29
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=1a60e4d516defb5808967a8b42ac6675a3f05085;p=users%2Fwilly%2Flinux.git

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.
