Subject: hfsplus: free space correcly for files unlinked while open
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=85b8fe8cc47b0dc1068475ba95f29ddff10a8efc;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

hfsplus: free space correcly for files unlinked while open

hfsplus_delete_inode only truncates away all block allocations if
i_nlink is zero.  Make sure we properly drop the unlink count even
when doing the rename hack for open but unlinked files.
