Good afternoon,

Could you please add the following line to the src/fs.h file :

# define S_MAGIC_GPFS 0x47504653

and add the following line to the switch() of the fremote() function in the src/tail.c file, in the coreutils package :

case S_MAGIC_GPFS:

or do you prefer me to send you a patch for these files ? (I'm not used to that yet, but I'll do it if you need it).

These addings fix a "tail -f" problem with the GPFS filesystem.

I'm waiting for your reply.
Thank you for your help regarding this fix.

Kind regards,

Martial Bornet
