Subject: [PATCH 7/9] [TRY 2] fbdev: Move arch-specific bits to their respective subdirectories
Date: Sun, 27 May 2007 17:44:46 +0800 [thread overview]
Message-ID: <4659530E.40102@gmail.com> (raw)
Move arch-specific bits of fb_mmap() to their respective subdirectories
Signed-off-by: Antonino Daplas <adaplas@gmail.com>
---
This version addresses some of the concerns raised on the first attempt except for the 2 points raised by Christoph Hellwig:
1. Make fb_mmap() required for all drivers.
This may entail more work as it will require that the prototype be changed to accept struct file.
2. A more generic name for fb_pgprotect().

Subject: [PATCH 7/9] [TRY 2] fbdev: Move arch-specific bits to their respective subdirectories
Date: Sun, 27 May 2007 17:44:46 +0800 [thread overview]
Message-ID: <4659530E.40102@gmail.com> (raw)
Move arch-specific bits of fb_mmap() to their respective subdirectories
Signed-off-by: Antonino Daplas <adaplas@gmail.com>
---
This version addresses some of the concerns raised on the first attempt except for the 2 points raised by Christoph Hellwig:
1. Make fb_mmap() required for all drivers.
This may entail more work as it will require that the prototype be changed to accept struct file.
2. A more generic name for fb_pgprotect().
