[Dazuko-devel] patch 1 for dazukofs release 3.0.0

[Lino Sanfilippo]

Hi all,

this is the first patch of a series of patches that fixes some bugs, 
that I encountered while
testing dazukofs on various platforms. Please apply the patches 
consecutively.
I will do a short description for each bug:


Bug description:
On 32 Bit systems large file support may not be enabled. This prevents 
processes from opening
files larger than 4 GB.
This may cause a failure of the dentry_open() function which is used by 
dazukofs to get a
file descriptor for an accessed file.
This failure results in the file accessing process hanging infinitely 
while the dazukofs kernel code
tries to get an open file descriptor again and again, always failing due 
to the file size limits.
The solution is to open the file explicitly with large file support 
enabled by setting the
O_LARGEFILE flag.
