FW: FW: mq_open
Hello gentleman, we have a problem with mq_open, shm_open and sem_open As stated in the manpage of "open(2)", the permissions of the created file are (mode & ~umask). But what is the use of the mode parameter, it it is not used like the programmers intention? On HP Unix or TRU64 the mode parameter is... 6 Aug 2010 07:10

[PATCH] regulator: max8660 - fix a memory leak in max8660_remove()
In max8660_probe(), we allocate memory for max660. In max8660_remove(), current implementation only free rdev which is a member of struct max8660. Thus, there is a small memory leak when we unload the module. This patch fixes the memory leak by passing max660 to i2c clientdata, and properly kfree(max8660) in max... 6 Aug 2010 01:45

[PATCH 29/43] memblock: Move functions around into a more sensible order
Some shuffling is needed for doing array resize so we may as well put some sense into the ordering of the functions in the whole memblock.c file. No code change. Added some comments.

[PATCH 01/43] memblock: Fix memblock_is_region_reserved() to return a boolean
All callers expect a boolean result which is true if the region overlaps a reserved region. However, the implementation actually returns -1 if there is no overlap, and a region index (0 based) if there is. Make it behave as callers (and common sense) expect.
