X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=94c1d3184523efa7109472eb393cee6e954c5d75;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [PATCH] Fix HFS+ to free up the space when a file is deleted. fsck_hfs reveals lots of temporary files accumulating in the hidden directory "\000\000\000HFS+ Private Data". According to the HFS+ documentation these are files which are unlinked while in use. However, there may be a bug in the Linux hfsplus implementation which causes this to happen even when the files are not in use. It looks like the "opencnt" field is never initialized as (I think) it should be in hfsplus_read_inode. This means that a file can appear to be still in use when in fact it has been closed. This patch seems to fix it for me.
